The combing effect you see during scenes with motion is the famous 
"interlacing effect". VLC doesn't implement any de-interlacer so, if the DVD 
has been encoded for an interlaced display (as opposed to progressive 
display) you can see such artifacts.
For a good explaination on the topic, go to:

The DVD input of vlc is not yet perfect, so a few DVD title may not work. 
(I've got one too). Specificaly, it's the IFO parser which is not yet perfect.

So you mean that sdl-config gives the right info but vlc doesn't use it 
correctly ?
