To quote: So I've finally gotten around to releasing 3.0. It's pretty much the same as in 2.99.534 except that you can now arbitrarily zoom the video via a setting in the popup menu.
I'm leaving on a vacation tomorrow and wont bring the PS3 with me so don't expect any (tested) PS3 features the next weeks. I will hopefully find time to do a bunch of other non-platform depended features though.
Once I get back I hope to address all aspects of audio on the PS3, in particular:
AV sync problems
Have a nice summer!

MKV DOES in fact play, the resolution and video quality itself is near perfect, if not perfect. But the rendering speed is quite slow, and the audio goes faster than the video causing it to go out of sync immediately. Also, subtitles are not supported.
