EasyCap

I recently bought a EasyCap recorder to record game play from my PS3 and other devices, I have encountered some problems and am still encountering them. On my windows 7 PC I get no sound, on a old old XP I get no audio, I will have to resort in using my main computer to hook up to use because windows 7 isn't compatible, and a windows XP service pack 1 isn't either, but the XP service pack 2 most likely is, or at least lets hope! Also if you didn't know the EasyCap is the $10 knock off of the EZCap, the EZCap is $30-$40, if you can then buy the EZCap if not then your getting what you paid for.
