I convert my movies to PS3 so I can watch them on my TV. I am also able to watch them on my iPhone with no probs.

My specs

Intel Core Duo Quad Core (overclocked to 3.2 MHZ)
Vista Ultimate 64 bit
8 GB Memory
DVDFab 5.0.3.0

I generally average 61.5 FPS and can encode a two hour movie in about 50 minutes

Hope this helps.... Tracy Ann
