I'm trying to troubleshoot a problem with my home theater system. My Phillips DSR-704 is connected through my Onkyo surround sound receiver. When I burn recorded Tivo programs onto my Panasonic DVD burner, the audio and video get out of sync. The longer the program goes, the farther out of sync it gets. I use the "Record to VCR" mode of the DSR-704 rather than "Play", if that makes a difference. I had a similar issue with my old DVD burner, so I don't think the new one is the problem. That means it's either the DSR-704 or the receiver. Is there any history of this behavior with the DSR-704?
