Your latest patches fixed all outstanding issues for me. Mythtranscode
really works great here. I don't see any green frames anymore and
there are no more asynchronous files. Thank you!

I just found one failing file with the following last lines:
2005-12-30 11:52:36.610 VID: B #:7 nb: 2 pts: 00:17:03.786 dts: 00:17:03.786

I've created a full log for this file and also an mplayer log (don't
know if you need both of them):
mythtranscode -i /big/myth/record/9_20051210184800.mpg -o
/tmp/test.mpg --show-progress -v all > /tmp/transcode.all.log
http://130.83.206.1/~egger/temp/transcode.all.log.tar.bz2
mplayer /big/myth/record/9_20051210184800.mpg > /tmp/mplayer.log
http://130.83.206.1/~egger/temp/mplayer.log.tar.bz2

PS: Is --show-progress supposed to work with mpeg2fix?
