I'm doing some TV capture off of my 3500. On playback of the capture the picture looks great but the audio gradually drifts out of sync. It's noticable after about 10 seconds or so. I'm running a P3 350 with 64mb of Ram. My hard drive is a pokey 8Gig Western digital. 3dfx recomends a 500mhz cpu minimum for capture... might this be the problem?
