Digital cable box and audio sync problem
 

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??:confused:

Unless the video and audio are actually going out of sync on your cable box, which is unlikely, I think it has to be your tuner card, Dzachau. I've had a few AIWs and VIVOs, but never a stand-alone TV card, so I don't know much about them. Perhaps someone here has experience of this issue and can help?

Otherwise, I'd suggest, first, visiting Hauppauge's site and seeing if there's any reference to problems like this in their support section, and also see if they host any forums. Commonly, problems like this can be features of particular drivers, or may need updates to your sytem. It's possible, particularly with composite or s- video, that better quality cables could help.

If you don't have any luck here, or if you do but want to check it out further, I would have thought you'd be able to find Hauppage group(s) (they're a very well known brand) on Usenet.
