Thanks, knicknak. That was going to be my preferred option if I don't maintain the original DVD format. I think converting the mkv to vob maintains the video format, correct? So it doesn't have to reconvert. It also streams using PS3 Media Server without having to be transcoded, which is a big plus too. The only thing in the back of my mind is that that format doesn't sit well with things like AppleTV or Front Row (and I use Macs). I'd have to use a Front Row replacement like Boxee/Plex/XBMC (which I might want to do anyway).
