The BBC HD test channel is broadcast over dvb-s in MPEG4 with MBAFF
encoding, it is not dvb-s2 (which sky hd channels are), so you can
receive it using a standard dvb-s card, I get it with my Technotrend
S1500 on Astra 28.2E BBC HD:10847:v:0:22000:0:2320:6940, unfortunately
 mythtv/ffmpeg cannot decode MPEG4 with MBAFF encoding in realtime, in
fact even the best H264 MBAFF codec (Coreavc on windows) cannot decode
it in realtime.

On my Core 2 Duo 6600 2.4ghz with 2gb ram and Geforce 7600 GT it plays
for a second or so, then stalls for 2 to 3 seconds, then resumes,
repeat.

You can record, and then transcode to xvid, that works and I did that
with the BBC Planet Earth series that were broadcast on BBC HD.

At this stage I think only set top boxes with dedicated H264 decoder
chips can handle realtime playback.
