Perhaps this is better described as video getting out of sync. It doesn't seem to matter what file is playing as how long it is playing for. When I wind-back and replay the piece of video it plays perfectly. Also I notice that the hic-up happens at about the same time from start of playback, i.e. 18mins approx, on each video.

Maybe this is just down to system settings? I am just using the defaults. Family use not making this easy to catch or adjust, but hoping to be helpful. Log also full of CEC log too as trying to debug that as well (I don't think there is any interaction between issues).

I've seen one other report that could be the same issue, but I'm not seeing any stuttering or sync issues.

Looks like you've got "PLL adjust" enabled in system/audio settings which is not a default option. Can you try disabling that?

OK, will try that tonight.

Some more detail. In the log I posted here http://forum.kodi.tv/showthread.php?tid=...pid2441242 "adjust display refresh to match" was disabled. Last night I enabled it as you recommended elsewhere, still got out of sync moments but a little later in the video (21 mins of play). However, unlike previously where there were a flurry of CDVDPlayerAudio::SyncStream messages, the log shows very little at the time sutter occurs. Just after the issue I hit pause on the remote, as I have CEC debug enabled this makes it easy to find these points in the log. My log is huge as I didn't reboot, so here a small extract so you can se what I mean,

Code:

At 20:33 I get a suttter and hit pause 7s later, nothing in log in the previous 27 minutes.

I know partial logs are a frustration, but this really does have the essentails in it. Hope it reveals something useful?
