PS3 recently released firmware that allows PS3 to play DivX video files. When I tried to play these from the Mezzmo media server PS3 gave me the "unsupported format" screen. I know I can play a DivX disk without a problem. I also made sure there weren't any spaces, long file names, or unusual characters in the files I tried playing. Can you think of a reason this would happen? I was able to play a few other formats, but I do love DivX quality.
