If I record BBC-HD I end up with what appears to be corruption - anything
from an almost perfect picture with a couple of glitches to a completely
unwatchable mess. Mplayer gives the same results when I try and play the
video captured by Myth. From what I can see, there are 4 possibilities:
1. The original stream from the beeb is corrupt - seems unlikely but I
guess it is experimental.
2. The data is being received corrupt due to interference or poor signal -
seems unlikely since I can get SD channels without any problem.
3. Myth is corrupting the stream while recording (e.g. it can't cope with
the data rate, etc.)
4. The H.264 decoder is broken/not complete enough. I guess the fact that
mplayer also has problems doesn't mean a lot since both Myth and mplayer
use the ffmpeg libs.
I'll play some more to see if I can narrow down the problem. It isn't
helped by the fact that the "signal quality" reported by the Nova-S-Plus
is always the same (even when there's no LNB plugged in!) so I guess it
hasn't been fully implemented in the driver.
