Here's a Freedom of Information response that suggests BBC News HD is always (at least) 10 seconds late on a story.
Distribution delays are essentially fixed for a
given platform and are a result of the time it takes to assemble all programmes (whether live or
recorded) and turn them into a form suitable for transmission. This process takes around 4s for
standard definition TV and 6s for high definition TV.
In addition, we add a fixed delay to some services on satellite to allow all our channels to
efficiently share capacity. [The capacity required by a given service varies with time so capacity is
dynamically shared between all channels; simulcasting programming on more than one channel,
such as with multiple variants of BBC One or the news on BBC One and BBC News Channel,
hinders this dynamic allocation process. Delaying certain services by a few seconds can allow the
dynamic allocation to work more efficiently.] Currently BBC One Wales HD and BBC One
Northern Ireland HD are both delayed by 2s each while BBC News HD is delayed by 4s.

Self-scheduling
They may be repeats, but at least you get a choice. The boss of the BBC's HD channel, Danielle Nagler, is offering viewers an online pick of 30 shows, from which she'll fill the Easter schedule. The ingrates who follow her blog posts are already at it. "Can we have a choice of resolution and bitrate for the programmes too, please ?"

Let's (not) talk
In the my younger days, the debate about quality in broadcasting was focussed on DAB, and whether it delivered digital sound better than/worse than a CD. The compromise was to declare it "near-CD-quality" (except, of course, when they squeeze the bandwith for 5Live).
Now the debate is about the quality of pictures delivered by the BBC's HD tv channel. 5 times more clarity than standard definition - or "more grain than my breakfast cereal" ?
Or at least there used to be a debate. Head of HDTV Danielle Nagler bravely blogged on the topic, and got her boffins to explain exactly what the BBC was doing to all those pixels. But after more than 1,200 comments, some of them apparently abusive, BBC blog policeman Nick Reynolds has, somewhat wearily (and rather early in the morning) blocked further contributions. Spool through to comment 1209.
"Sadly despite my final final warning people are still posting abusive comments. So I will close this post for new comments today. It will be closed for a week. I will then decide whether to reopen it again or whether there are better ways of continuing the conversation".
Other forums, including DigitalSpy, have taken up the dialogue.

HD error
I stand corrected on Virgin's HD offer - if you take the XL package, you get more, including Channel 4 HD, MTV and FX HD and National Geographic, says Broadcast. But it's odd that as a long standing customer, I got that wrong....
