I tried. If it did improve, than not noticeably.

Yep, in the meantime I watched larger parts of the film and it seems like 
chunks of more than a minute are skipped.

By the way, manually going forward or backward in the stream leads to minute 
long searching of mplayer again.

I will start with the following: I will specifically ask, which windows 
program and try, whether this program on another machine works. Next I will 
try to get access to the dell machine with Linux/mplayer. I will try to 
convince the owner of the Dell computer to let me use DVD Shrink on his 
machine, however, this I can do on Monday earliest.

You are right, mplayer -dumpstream does not seem to do something useful.

I really, really appreciate your effort. Thanks.
