Please keep mplayer mail on the list! If everyone I replied to on the
list mailed me personally, my personal mail inbox would be overflowing
all the time (even more than it already is!).
With that said, the file -dumpstream produces is perfectly good; it's
just that mplayer can't seek correctly in DVDs to begin with. You'll
notice the same problem if you try to seek with mplayer -dvd 1 -ss ...
The best solution is simply not to use seeking for ripping DVDs.
There's a perfectly good -chapter option for this which will seek
right to chapter boundaries, so you don't cut your rip in the middle
of a scene (which is super-lame). Unlike most options, -chapter also
works with -dumpstream, so you can do something like:
mplayer -dumpfile part1.vob -chapter 1-10 -dvd 1 -dumpstrea
mplayer -dumpfile part2.vob -chapter 11-20 -dvd 1 -dumpstream
The other option is to repair mplayer's seeking so it actually works,
but that's probably best done after the demuxer layer is rewritten
(planned to happen eventually, but not soon).
