I'm willing to work on some code if you can help me get started :)
For some reason, ps3 lists pause/etc. as grayed out.. guessing it treats
transcoded stream as a live stream which can't be paused
One trick that could be used is transcoding to a temp file and then
feeding it to PS3 as input. That would require extra HDD space/access,
so I wouldn't make it a default, but it would make life easier in some
cases.

Neat, 720p content looks much better now! Though it's freezing every few
seconds... any chance to use multiple CPU cores for transcoding process?

 It's a bit hard to watch foreign content without any translation ;)
