Core AVC
When I first started with Fab i had an old, very old PC and Core AVC worked very well with my DVD's!
Last December I built my first PC and also upgraded Core AVC, and come to find out it was slower to use it, I have a Nvidia card and set everything to cuda and cuda+software! This is where I get my fastest times!
For me Core AVC and software were very slow times!:) Also for h264 and everything else cuda!
