ok, i spent ages looking for a AVIVO solution for x264's, no program was having any of it. Cyberlink h264 avi decoder wasnt even working.
Then i found MPC-HT with EVA and x264 DXVA support! and i finally got it all working.
I just played a XVID, and realised it was also working through AVIVO! but DXVA is turned off for xvid as shown in properties, yet it was still working! and I just cant understand why. Obviously its a good thing it was working but i REALLLLY want to know why.
Can any one explain?
