All of you,

I think it's time to give op on this issue. We will properly never have perfect playback with the hardware of nowadays. The main core of the problem seems to be this:

1. Video cards of nowadays are not capable of playing material at steady 23.976 HZ.

2. The Old audio engine was definitely a cause. The new one is much better, I would say almost perfect.

3. The Sync options are not making things better, they are making it worse. All the custom setting people are applying to the new builds, especially the openelec builds, are not gonna help for so far I know. My personal opinion: The less sync options used, the closer you are to perfect playback.

I have recently tested a new frodo build form this website: http://www.xbmcfreak.nl/xbmcbuntu-12-04-...y-release/

This is the first build I have ever seen that finally play's the movie in sync with the audio. I would say it's almost perfect, or maybe fully perfect. I can't tell exactly because there is another factor that has influence on this, and that's the hardware issue, the incapability of video cards to play at 23.976 hz.

So for all of you considering to give it a last try, try this new build. Keep all settings to standard. The only thing you need to do is adding a 23.976 modeline to the xorg.conf. No sync options. They only mess things up. The only option you need to turn on in xbmc is the "Adjust display refresh rate to match video" option. This is not a sync option, it's just a mechanism that chooses the proper modeline from the xorg.conf or the correct mode from the video card's EDID.

Give it a try,

so your option to fix the sync issue is to turn the sync off? So if the ABS brakes don't work in a car, and there is a little light warning you they don't work, we just cover it up with a piece of tape and move on right? True story by the way. So that is what you are suggesting, just ignore the warning light that it doesn't work and everything will be great?

Adjusting refresh rate to display only changes to the closest refresh rate or multiple that it can use. Depending on the video card and how close it is, this may work okay, but then you will get frame drops, thats the whole point of the sync is to not have frame drops because you can resample or drop/dupe the audio to keep it in sync with the video.

Reclock does this fine so why would people not do it correctly? It works fine with 50hz refresh when watching 25FPS material, it works fine with 60hz when watching 29.9 fps material so its obviously a programming issue in XBMC.
