Hello! So problem is - I have two blocks - one with nVidia 9600 and another with ATI 4850. In all blocks use the same Vista Ultimate and latest drivers, the same codecs. With nVidia card EVR works, but at ATI card with EVR "on" the screen is black and only sound hear. So with ATI card I had to use VMR9. Is this programm bug, or I must make some changes in ATI control center?
