- Channels (queries on individual services)
- Digiboxes (queries on the receivers)
- Widescreen (specific queries for widescreen operation)
- Teletext (for both analogue and digital text)
- Miscellaneous


- Why can't I get the 'foreign channels' any more, even if I "add" 
Sky Digital comes from a different satellite than analogue Sky; this new 
satellite, Astra 2, does not carry any foreign channels that are in a 
format that the Digibox can use. The only foreign channel that is 
available is CNE (China News and Entertainment); this must be tuned in 
manually from frequency 11.758 H.

- What other channels are available by using "add channels"?
Testing services include:
12.129V B4U (Bollywood For You), asian channel, testing 12.178H "1951", an 
additional MusicChoice channel
12.178H "1952", an additional MusicChoice channel
12.178H "1953", an additional MusicChoice channel
12.192V "S4C2", a promo video for the forthcoming S4C2 channel
12.238V "1713", a copy of the Sky Info channel
12.238V "1707", a SkyDigital held graphic with music track

- Can I get any other channels?
Yes, for free, too. S4C (a Welsh-language channel but with English 
subtitles for most programmes on teletext page 888) is available free to 
any digital satellite viewer in the UK, but you need to call S4C to get 
switched on, since for copyright reasons you must "subscribe" seperately 
to the service, even though subscription is free. Call 08705 663 3630 to 
get switched on (which is a bilingual telephone number, so don't worry if 
you're answered in Welsh!)

- Where's Eurosport?
British Eurosport launched on SkyDigital on August 1st. However, it does 
not currently appear in the channel list in the SkyView magazine. This 
channel is slightly different to the European Eurosport on analogue Astra.

- When is ITV going to be on Sky?
OnDigital is majority owned by two large ITV contractors, and ITV itself 
is broken up into 35 sub-regions. It's unlikely, for the moment, that ITV 
will make it to SkyDigital itself. However, an add-on for the digibox 
called a "sidecar" will enable reception of terrestrial digital broadcasts 
on the digibox within the next few months. Rumours have suggested that 
Scottish Television may appear on SkyDigital, along with support channel 
S2; it's likely this will be for Scottish viewers only.

- I though I was supposed to get my own local TV news
BBC 1 in England only broadcasts a generic local news programme called "UK 
Today" (which, in fact, consists of English news stories). Incidentally, 
this is also carried on OnDigital at present; local programming is only 
available in analogue.

- I DEMAND BBC Wales/England/Scotland/NI. [Delete one of the four]
BBC 1's regional programming is strictly controlled by contractural 
rights, so if you live in Wales you will automatically get BBC 1 Wales. 
BBC 2, however, is a generic UK-wide version of the channel. The 'other' 
regions of BBC Choice are, however, available to everyone.

- Is it true you can't record Sky Box Office movies?
Yes, that's mainly true - they use Macrovision (which, incidentally, 
OnDigital and DVD also use). Sky say that most movie-makers insist on copy 
protection for pay-per-view channels. Not all Box Office movies (though 
the vast majority) are copy protected - any copy protected programme is 
marked "C" in the information section of the EPG.

- How does Macrovision work, then?
It works by adding extra brightness pulses into the part of the signal 
which the TV doesn't normally display because of overscanning. The 
brightness pulses upset the automatic level control of the video which 
ends up overdimming the picture. Macrovision blockers are available, but 
are illegal to use in the UK.

- How come the FTA channels aren't FTA?
FTA = Free To Air, meaning that you can watch them without a card. FTV = 
Free To View, meaning that you can watch these channels without 
subscription, but you will still need a card for copyright reasons. Cards 
are free for non-subscription television, but all subscription cards (ie 
Sky) are enabled anyway. There are some FTA channels on SkyDigital, which 
are available without a card. For a full channel list, including FTA/FTV, 
check the Media UK Internet Directory at

- Where's BBC Radio?
A reply from the BBC earlier in the year indicated that the BBC are not 
planning to bring their radio stations to the SkyDigital platform. 
However, later comments from BBC executives seem to suggest that a BBC 
service, including regional stations such as BBC Radio Wales, may be 
available on digital satellite before the end of 1999.

- Why doesn't Skyview, the subscriber magazine, list all the programmes 
Sky decided that the EPG (Electronic Programme Guide) was enough for most 
people, so removed the limited programme listings in the magazine. Never 
fear; comprehensive (and interactive) listings are available through a 
piece of software called "DigiGuide", which runs on your PC. For more 
information, and to download the software free, check out, where you'll also find normal HTML 
programme schedules for virtually all SkyDigital channels.


- What's the best box?
The boxes themselves run almost identical software and hardware. All boxes 
offer the same features. While different manufacturers have different 
reputations for reliability, it isn't obvious that any one make of box is 
less reliable than any other. Boxes are now being manufactured with a 
faster processor than earlier models: you can spot the difference by 
looking for the "*" symbol on your EPG's digibox information menu screen.

- How much do they cost?
The full price of a Sky digibox is 280, plus obligatory installation at 
100. If you agree to subscribe to Sky for a minimum period of 12 months, 
the installation falls to 40. If you agree to having your phone connected 
to the digibox (see below) then the cost of the box reduces to 0. Neither 
of these subsidies is dependent on you taking the other, so the total cost 
could be 40, 100, 320 or 380.

- Do I get a choice of box?
Not really, although there's nothing to stop you asking nicely. If you go 
to an independent dealer, rather than one of the chains, you stand a much 
better chance of getting the box you want (and an earlier installation, 

- How can I get an extra remote control?
CPC sell the standard Sky remotes. Their order code is HS00352, and they 
cost around 16 plus P&P. You can access the main catalogue and order on 
the web at

- And what about the TVLink thing
TVLink is available from 0870 333 7775, for 14.99 inc VAT and P&P. It 
allows you to control your digibox from a second TV, and also acts as a 
distribution for your normal terrestrial TV channels too. It uses coaxial 
cable, which you need to buy and fit yourself. It works fine, although 
other equipment (the author has a "Rabbit", but remote control extenders 
are also available) would allow you to control your video, DVD etc too. 
(The author's Rabbit uses wafer-thin wire, which is easy to chuck under 
carpets without being noticed, but I can't find new Rabbits these days.)

- What's with this phone connection?
The phone connection is primarily for Open, the interactive television 
service, for e-mail and purchasing goods. It is also used by Sky and 
UDirect to communicate which pay-per-view events you've bought. It is 
unclear what other information is transmitted to Sky through the digibox 
phone link. The phone connection is not obligatory, although most people 
agree to it because it gives you money off your digibox.

- Do Sky telephone the box?
No, the satellite tells the box to phone home, which it does (through an 
080 freephone number). It will check whether you are on the line first.

- It won't work without the phone connection, will it? Bwah.
It will, but your contract probably requires the phone connection anyway - 
at least for the first twelve months. Sky BoxOffice events are still 
bookable, but you'll need to ring customer services.

- Where's the timer/programme planner/digital teletext?
All these features are currently being programmed. An e-mail from Sky in 
late August reportedly says "I can tell you that Sky does have plans to 
introduce a timer feature that will automatically turn the television 
channel at the appropriate time. The exact launch date has not been set 
but it will likely be late Autumn and definitely before the end of 1999. 
When this new functionality is added, you will also get a "personal 
planner" that will allow you to input your favourite programmes and a 
reminder will come pop up on your screen just before the show is scheduled 
to start."

- My signal strength seems a bit low - is this a problem?
Only a problem if your picture freezes. Some digiboxes seem to report the 
signal strength in a very different way to others, and upgrades of 
software seem to change the signal strength meter software.

- When was the last time the software was updated?
The last update of the software seems to have been in early August, adding 
favourite channels, Sky Sports Extra software, and Open's interactive 
software. More upgrades are expected later in August. Amstrad boxes 
received the upgrades later than others.

- What's this "Open" thing?
Open contains film reviews, games, home shopping, and other information, 
available by pressing the "Interactive" button on your SkyDigital remote 

- How do I force a software upgrade?
Remove your card. Switch the box off at the mains. Press and hold the 
backup button down on the box, then switch the mains back on. Wait for 
about 20 seconds, until you see a message appear on your television (which 
only appears on a SCART lead). Follow the instructions (ie don't do 
anything for the next ten minutes).
Forcing a software upgrade is not actually required, since Sky upgrade all 
box software automatically; furthermore, both new and old software is 
transmitted simultaneously, so if your box hasn't been told to upgrade, 
you may still receive the old software.
Experience in August shows that many boxes download upgraded software, but 
do not activate it until you switch the box off and on (by using the 
remote control). When Sky wish to upgrade your box, they simply send it a 
signal to switch off.

- How do I reset my box?
Remove your card. Put Digibox in standby. Switch the box off at the mains 
for at least 60 seconds. While unplugged, wipe the gold contacts of the 
card carefully with a dry tissue to remove any static build-up. (Note: use 
a tissue, not a jumper!) Switch the mains back on. Switch Digibox back on 
(it'll boot up for around 20 seconds first). Insert viewing card when 

- How do I access the Installer setup menu?
Services - 4 - 0 - 1 - select. Be careful what you change.

- Can I change the preset channel numbers?
Unlike OnDigital, you can't. This is primarily for marketing purposes, so 
that (for example) BBC Knowledge is always on channel 553. There are a few 
regional differences to channel numbering; for example, Channel 4 for 
Welsh viewers is on 184, while Wales's own fourth channel, S4C, occupies 
the 104 channel slot.


- What's in widescreen on SkyDigital?
BBC1, BBC2 and Channel 4 show various programmes in widescreen. Sky has a 
dedicated movie channel for widescreen, but also occasionally shows 
widescreen films on its regular movie channels. A few BoxOffice screens 
are widescreen, and the U Direct pay-per-view film service are all 
widescreen. Additionally, Sky's premiership football coverage is now in 
full widescreen, though not Sky Sports Extra, and during the summer they 
experimented with live cricket coverage in widescreen. The sound, 
incidentally, is usually Dolby Pro-Logic (although many programmes are 
just in stereo).

- I have a widescreen TV, set to "wide", and my digibox is set to 16:9, 
but some non-widescreen programmes don't fill the screen, and leave me 
with vertical black bars. Why?
Currently, S4C and Welsh/Scottish/Northern Irish versions of BBC1 are 
transmitting a permanent widescreen flag which means your television will 
think everything is widescreen on those channels. This is fine when 
broadcasting 16:9 widescreen programmes, but not so fine when they 
broadcast 4:3 programmes, which appear with black bars to the left and 
right. Both broadcasters are planning to change this.

- I have a widescreen TV, but some films still have bars at the top and 
For a "normal" TV, the ratio is 4:3 (i.e. it's "four" wide, and "three" 
high). For widescreen, it's 16:9. But for some widescreen films, the ratio 
of width/height is 2.35:1 - which is even wider than TV widescreen. The 
bars at the top and bottom of the screen are therefore still there.


- Is standard teletext still available?
Unlike OnDigital, analogue teletext is available, but not on all channels. 
Digital teletext, "SuperText", is due, according to Sky, to be "available 
this autumn and definitely before the end of 1999". Currently there is no 
sign of it - however, the BBC Text data does appear to be being broadcast 
- just that the software isn't finished yet. OnDigital subscribers are 
also seeing some data, and it's currently under test there - for a 
preview, try, and for real 
screenshots of Digital Text working, try

- Where's my teletext gone? I'm sure it was here yesterday...
An early bug meant that, occasionally, teletext did not get received 
properly by digiboxes. This was fixed, but appears, after the latest 
upgrades, to be a problem again. To get your teletext back, reset your 


- Is the picture affected by weather?
Normally, no. In a very heavy thunderstorm, either where you are, or where 
the uplink to the satellite is, then sometimes you may get slight 
problems; the author's box locks up in a very heavy thunderstorm.

- How can I get Sky outside of the UK?
Go and see
