I am trying to set up my computer as a PVR. In order to do this, I need to run audio/video cables so that I can send data both ways. i.e. I want to run the video from my reciever to my computer, then record it, then be able to send it back to the reciever. Is it possible to do all of this with one cable running from my reciever to my computer (they are in different rooms). I have video in and out on my ATI AIW 128. I know that this is very easy if I just run two sets of RCA cables, but my wife would kill me. Thanks in advance.
