The heat is getting on my nerves, so this is more of a rant than a reply
So, it seems like some are a little too concerned about the 'wrong' kind of content going HD (like BBC1 for instance). Why? isn't HD is as good as encryption itself? LOL. For a start, the price of HD kit is still a joke and don't even think of factoring-in that sony widescreen you bought last year.
From reading the thread, I suppose they could just move back all the crap to 2A, like Parliament, iTV feeds that don't work on my SKY box and that BBC News 24 thing - but why bother ?
I'll be honest I'll be more interested to see how the BBC intends to piggy-back on sky's HD (such is my assumption

) - all of which requires a new subscriber STB (as pointed out).
Tone shifts to my perennial gripe with the BBC on/using SKY.
Its just my beef, but, I think that there has to be a limit as to the number of times SKY let's the BBC come round only to nick all the twiglets, drink the stash of Bud and leave without thanks. Like, SKY makes the investment - the BBC bareback the platform. HD will be no different. Time for change me thinks.
PayTV SKY will show HD sport and movies; unlike the BBC which will first have to wait for SKY's launch (sic) and will then, probably, soft-launch its own service with an HD version of the Lottery show, News at Ten and Fawlty Towers with a logo in the middle of the screen.
I'm confident that after the BBC
re-broadcasts Germany's HD World Cup in 2006, the government will herald the BBC as an HD champion.
Whatever, me thinks that there must be a point where even the domestic PSB's realise that having their own branded satellite proposition is workable if they stopped leaching off SKY.
There is a gazillion BBC channels, soon to be 4 ITV channels + News, Channel Whore will milk every last drop of bandwidth they can and RTL have never missed a trick with Channel Five.
Have fun,
Mark.
P.S. still doing homework on the symbol rate, maybe some techy can help. Euro 1080's symbol rate is 27500 - 3/4. So perhaps this is another factor to bear in mind with the Beeb's aquisition of space on 2A, since the typical rate on 2D is 22000 ??? Is the latter rate sufficient for HD ??
