Ihave a Hauppauge TV tuner card (350 PVR) that is hooked up via composite cables to a digital cable box. After a couple of minutes the audio and video start to go out of sync. Eventually, the picture starts to get very jerky, as if the fps drops off dramatically. The problem dissappears if I run the coaxial cable directly to my tuner card and bypass the digital cable box. The problem with audio sync is also corrected if I turn off my tuner software and then back on, but it eventually returns. I can just dump the box, but without the cable box I lose the movie channels. Can anyone tell me if there is a known fix for this problem??
