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!
