Im experiencing a problem with libxineoutput. The video and audio are out of sync. the settings for the plugin correct it good for one channel, but then are out for another channel, so Ive had to put it in the "middle" so its kinda out of sync equally across all channels, but I find it unacceptable. I also have an A/V sync problem on another machine playing DVD's, where mplayer is fine, so I suspect it to be xine-lib, rather than the plugin, I am just wondering if anyone else has seen this. VDR 1.4.0, CVS libxineoutput. Latest xine-lib 1.1.2-r1 I believe.
I shoud note that Im using spdif passthru. the DVD playback on another machine is regular analog.
Thanks

I'm also experiencing A/V sync problems with xineliboutput. They appeared when I switched from analog audio to spdif passthrough.
I haven't been able to correlate the problem with anything specific but I think the format of the audio has an impact to the severity of the problem: AC-3 streams are more likely to be out of sync than PCM streams.
I also have occasional audio drop-outs. It is possible that they are caused by the coax cable but I suspect it might be software problem.

Some research shows that xine-lib 1.1.2+ is the problem, but I cant get 1.1.1 to use XvMC(nvidia). I experienced the same A/V sync problem on another machine playing back a DVD.
So... I can use 1.1.1 if I can get it to work with XvMC.. for some reason it wont use it, although it compiles fine and says its available but always falls back to plain XV anyways.

I have always had audio drop outs on AC3 streams, but not PCM ones, the 5.1 ones on some channels isnt even useable, others will drop 3-4 times in a few hours. I have this problem with softdevice and libxinoutput and the xine plugin.. It didnt do it at all with one digital receiver at all, but my new one does it.
