This looks like interlaced video. I think 3 pass encoding does not work with these. If that's the problem you are facing, just rm frameno.avi and do -oac mp3lame during all passes and it should be ok.
although your idea to use 2-pass encoding instead of 3-pass seems to work, the video is not interlaced! (transcode can detect that) any idea how i can draw the developers attention to that problem? the sample .VOB and problem description are still in the incoming dir on the ftp server...? i've tried reporting the bug on the mplayer-users list but it was ignored... thanks, julian
