Which channels don't work?

I've just tried this for BBC Three BBC Four (which are currently
off-air until 1900) and Virgin ! +1 (back on at 1800) and got the
off-air placeholder text (saying e.g. "BBC Three is available from
7.00pm daily..." and could use the OSD browser or direct channel
number entry to change to another channel. These are the only 3
channels on UK DVB-T that I might tune to in LiveTV.

I guess success depends on the particular broadcaster and whether they
provide MHEG data/graphics to permit "tuning" to an off-air channel,
but since the introduction of the MHEG interactive TV browsing I don't
seem to have gotten stuck on these channels before.

Cheers,
Nick
