View Full Version : Sound sync problem on WinTV PVR350 output

I'm not sure whether this is GB-PVR related or a problem with the TV card/drivers. Whenever I play back a recording in GB-PVR and I use hardware decoding (WinTV PVR350s own output) the sound is slightly out of sync. The sound is slightly before the video. It's not very far out so you can't see it most of the time but sometimes it's really obvious. I'm still a bit unsure as to whether it starts off this way, or gradually goes more out of sync as the recording progresses.

The output from the WinTV card goes into the TV via a scart lead (both video and audio).

When I play using software decoding, it seems in sync, but the framerate is low / jerky so it's possible I'm just not seeing the sync problem.

I can't see it being related since it's entirely different hardware but I've also been having audio sync problems (again, sound slightly before video) when playing back DVDs using the ATI 9600s S/PDIF out (but not when I use the sound card's analogue out).

This seems to be a very common problem, with different solutions. One that worked for me was to keep the disk defragmented.
