Sorry for ansvering myself, but...

Hmm.. maybe the problem the problem is due to limitations in the avi
container format (the 2GB thingy)? Can i rip raw video to mpeg container
format? Or can i somehow get *lossless/lowloss* mpeg2 movie directly
(*if* my pc can encode it quicly enough)? Sending it over LAN in
realtime to a more powerfull computer, and code it there? I am planning
to write the movies to DVD using DVDStyler.

What audio format does a normal HW DVD-player use?

But there are still those bugs kicking around...
