I have a RADEON X850 XT Platinum Edition graphics installed in my PC. I also have a Sky + system installed. I want to copy recordings I have made on the Sky+ system to my PC. I have been told that my graphics card is capable of video capture and that if I run an s-video cable from the Sky+ box to the graphics card and have video capture software installed (like Cyberlink Power VCR) I will be able to transfer the recordings this way. Is this correct? If not what other equipment and/or software do I require?
