Actually it's more complicated than that. I'm still not convinced the
ts contains only one channel. See below.

I've uploaded a sample to
ftp.mplayerhq.hu/MPlayer/incoming/soyebhdsample.ts . The sample is
about 70MB. I'm sorry for the large file size, but the files are
enormous even for a few seconds of recording.
If I play the sample with simply "mplayer <filename>" then it plays one
channel, but if I try "mplayer -nosound <filename>" then I get another
channel and the repeating error:
[h264 @ 0x87c3808]MBAFF + spatial direct mode is not implemented
There is one possibility, I had to change channels in VLC whilst
recording to get the correct channel recorded (VLC always chooses the
wrong channel to start with), so could it be a bit of recording from the
first channel then the second channel? But if that's the case then why
does the first channel only appear when I'm using -nosound?
