That's exactly what I did. I looked at all my second-tier DVDs and decided I didn't care about the special features beyond perhaps the commentary tracks, so I decided to go with MKV. It cuts down on the site a decent amount. I just watched one of my ripped movies on my Boxee Box the other night, and it looked great and was a nice convenience (over the very difficult process of getting up and putting a disc in a tray ).

Thanks for letting me know about the update. I was wondering about that. They'd tweeted something about how they were waiting to release the update until they worked out a bug in the vudu app (so I guess that particular app can't be updated separately). In the same tweet they stated that it would be released yesterday whether vudu was working or not, and I guess they technically weren't lying
