The simplest set I've used is the same as I wrote in the last mail:
mencoder -oac copy -ovc rawrgb dvd://1
Apart from that I've used:
mencoder -oac copy -ovc xvid -xvidencopts pass=1:bitrate=1000 dvd://1
mencoder -oac copy -ovc xvid -xvidencopts pass=2:bitrate=1000 dvd://1
But as this is a bit more time consuming I'm only testing with rawrgb
atm.

It doesn't seem like it's related to what processor you use.

I've soon tried them all :)

The same on all of them.

I'm quite sure mplayer isn't the source.
I could try ripping the sound from the vob/dvd and merging the sound &
encoded video with another tool (like ogmmerge), but I do believe sync
would just get even worse. I've tried this once earlier, but it didn't
work very well.

Yes, I mentioned this a week ago or so. I did read thru alot of old
emails trying to find similar problems and solutions, but I only found
similar problems. However, I recall one mail from 30th January 2003 (I
think) that said this problem occured somewhere after the cvs build of
11th December 2002. I admit that i didn't try this version too much, but
that's because I had troubles getting XviD to work with it. Someone
claimed XviD wasn't supported in that version.
