I tried that under MPlayer. With native demuxer there are no problems.
With -demuxer lavf libmpeg2 shows artifacts when seeking back and -vc
ffmpeg12 crashes. So there might be 2 bugs in ffmpeg, one in libavformat
producing invalid output and another in libavcodec causing a crash on
invalid input.

Decoding with libmpeg2 and ffmpeg12 also gives different aspect ratios,
1.78 vs 2.37. I think 1.78 looks more correct.
