Preferred settings for playing DVD content?

[ajkessel]

I'm using VLC to play DVD content (either directly from a disc or from a VIDEO_TS directory structure) over VGA to a 1080p/24p HD projector. The image/motion quality is much better and smoother with WinDVD than VLC. With certain DVDs, especially cartoons, the edges of objects are somewhat jagged during motion, almost like poorly aliased fonts. I believe this is interlacing judder although I'm not certain; I do know I don't see it when playing the same content with WinDVD.

It seems like 24p DVD content should be somewhat standard -- are there "best settings" for playing this sort of content? Activating a deinterlace filter seems to improve things, but I was under the impression that you shouldn't need to deinterlace if you can output at 24p. It's not clear to me whether this is a hardware or software limitation -- but I must have a very common scenario here. Can anyone point me in the right direction to a simple fix?

deinterlacing depend on the INPUT not the output.

Input is standard commercial studio-produced DVD video. Shouldn't there be a sensible default for this very common use case? What is WinDVD doing?

I also realize the interlacing issue is separate from 24p. Can I get vlc to play DVD content at 24p?

On further research -- I think what is needed is an inverse telecine filter for DVD content. mplayer for linux supports this but I haven't gotten it to work on mplayer for windows. Has anyone made any progress with IVTC for VLC? Is this possible?

Same problem here. What I observed though, is that quite often the feature film on a DVD does play correctly (but maybe the content is not interlaced to begin with) whereas the extras suffer from heavy (de-?)interlacing artefacts.
