Likely just unusual timestamps in the VOB/MPEG-TS.  As mplayer isn't
altering the container at all, it can't fix anything with -dumpstream

The timestamps can be fixed with mencoder or ffmpeg told to copy the video
and audio and only remuxing the container.


If I run this command instead:

You have to tell mencoder what bitrate to use for the video (or perhaps crf
with x264) to select the quality you want.

Assuming an NTSC DVD (North America) you also need: -ofps 24000/1001
And you may need pullup or pp=lb.
