Hi all…not claiming to be an expert by a long shot but a few months ago I went through the pain of trying to nail down a solution to get DVDs ripped through my OpenSUSE system and playable with no further conversion on my Creative Zen. I had problems with A/V sync, until I got the right settings figured out.
I came up with a script that front-ends Mencoder. This works great for my Zen, and should be able to be easily tweaked for many other applications. Here’s the link:

Hope this helps someone who may search in the future…
