i have the winfast tv 2000 xp deluxe and want to record from vhs. unfort, my vcr and vid cam are both somewhat ancient. they dont have any s-video output--only rca jacks. the card installed and plays live tv just fine. but when i click the Input Source button i cant seem to get it to use my vid cam as the input. i used the s-video splitter cable that came with the product. i plugged the video out from my vid cam to the rca jack and left the s-video input empty. is this possible?
