Audio & Video Progressively Out of Sync

[Snuffy2]

I'm not sure whether this is a Beta issue or a Sage issue in general, but I've only noticed it happening in th epast week or two. Mostly because I've started to watch a lot more TV movies.

When watching recorded shows, it seems that, the longer the show, the more the audio & video become out of sync. For an hour show, I don't notice it. But for longer (like last nights superbowl) by about 2 hrs the audio and video are 0.5-1 seconds off.

Some stats:
SageTV 2.2.5 RC
Win XP Pro
P4 3ghz machine
512mb RAM
Outputs through PVR-350
Additional PVR-150 as 2nd recorder
Video Decoder: SageTV MPEG Video Decoder (Overlay)
Audio Decoder: SageTV MPEG Audio Decoder (Default Renderer)
Cayars 17 STV

Does anyone have any ideas as to what might be causing this? Note that it happens with or without ComSkip.

Thanx

if you are using the outputs through the pvr 350 then you are not using overlay/sage decoders

thats for software decoding
and not sure what your issue is but report a bug

If this is when using the 350's TV + audio out, I would count it as a problem with that card, since it has been mentioned around here before. If you do a search for something like 350 sync you'll find a few threads including this one: Audio Not in Sync w/ PVR 350 TV Out

I have this problem and I have not been able to find a solution. I have just tried emailing hauppauge support. I guess I'll wait and see what they suggest.

There is no true solution. One suggestion is to cool that chip with a good slot cooler, it seems to help but is not a fix.

In my case they took my number and email address and told me if engineering ever figured out a problem they would call me. No call so far. Here's the issue IMO, they have a hardware design defect that no amount of software can repair.

I wish I had never heard of that card.

[RobDMB]

Its a shame if there really is a design defect. It seems every decoder card is limited in some way. This card can't keep the audio/video in sync and the xcard can't display more than 256 colors in the UI.

and the xcard can't display more than 256 colors in the UI.

True, but you don't watch the OSD for entertainment. 256 color limitation is a better price to pay rather than audio / video sync in my opinion.

But I get your point. Too many short comings no matter where you turn.

OK, can anyone reccomend a good, quiet slot cooler?

I also have this problem. I am using the PVR 350 tv out and audio out, and the audio gets more and more out of sync. If I set hardware decoding only to false - I can see that the software decoded audio and video is in sync, but the 350 tv output is not. Also I have found that the audio remains in sync when using the 350 tv out and Hauppauge WinTV. So I don' t think its a hardware or driver problem.

Has anybody else tried testing with WinTV instead of Sage? Does the sync problem go away?

[cummings66]

Yes, Hauppauge will not talk to you unless their bundled software does it. I was able to confirm it does it as well. The longer the recording the more out of sync it gets. Once in a while the thing is out of sync from the get go, but not all the time.

I have no idea of why, Hauppauge has no idea of why beyond suggesting it's heat related. I asked if the heatsink could be removed and a better one installed and they said no.
