Hi Michael Niedermayer!

I don't know that it help to the solving. I have two watching:

1, use dvdnav with libmpeg2:
If last status code of frame is STATE_SLICE then decode still frame OK
If last status code of frame is STATE_END then libmpeg2 can't decode

2, play test mpeg file:
mplayer -fps 1 -vc mpeg12 frames.mpg
V: 1.0 1/1 ... show: don't draw
V: 0.1 2/2 ... show: don't draw
V: 0.5 3/3 ... show: frames "01"
V: 0.6 4/4 ... show: frames "02"
...
V: 0.8 9/9 ... show: frames "06"

mplayer -fps 1 -vc ffmpeg12 frames.mpg
V: 1.0 1/1 ... show: don't draw
V: 0.1 2/2 ... show: frames "01"
V: 0.5 3/3 ... show: frames "02"
...
V: 0.8 9/9 ... show: frames "07"
