I'd be interested to hear how yo get on with BBC HD in mythtv.

I spent some time over the weekend trying to find out why playback
wasn't as good as mplayer (with or without directshow filters). Even
with coreavc and a Core 2 Duo E660, myth still skips frames even
though neither core is running more than about 50% (mplayer is fine).
I have a small test app that just plays back frames as fast as it can
and that gives me 35-50 fps when using coreavc and if I disable sound,
playback is absolutely fine.

There's something strange happening in the a/v sync process but I
haven't tracked it down yet...
