Tversity is a garbage program. Lets get that clear. Ive never had it run 100% right and always mixed results and runs like a turd. I finally stumbled upon PMS (PS3 Media Server) and it is the most amazing software ive ever witnessed.

There is the website. The only issue i had was that i couldnt get VC-1 (WMV) working but it was due to older WMV codecs in the package, link to those are here:

Copy the proper files over and you're set. It encodes ANYTHING that doesnt work on the PS3 to MPEG2 on the fly including audio to DD 5.1 or even LOSSLESS PCM 5.1! So basically ANYTHING works as long as your PC is up to it. I have a 2.93ghz dual core intel setup and ive yet to find anything that doesnt work.
