How do I display my TV screen on my computer? So i have a ps3 and i dont have enough money to buy a HDPVR but it could work to download a recording program to my computer and then put a cable from my tv to my computer to display my TV screen on my computer and then record the tv screen? Which cable do I need to do this?
