So, to wrap up a review I started a long time ago.

So I took a good look at the files and I had an xvid at 704x400 (I cropped a little) and an ogg theora with 720x480 resolution. Generally speaking, the ogg theora had much better audio/video sync. Throughout the entire film, the audio was just as in sync as on the DVD. The xvid file lost sync little by little, but never to a ridiculous degree. (Although it has happened to me with other discs)
