Been a while since I waded into this, but for those who have had success with AE (both for bitstreaming and sync) I'm glad to hear it.
For those who still experience issues with sync (I never have or at least have never seen it) I'm not sure what to tell you. I've not heard of a single dev who sees it on their rigs, at least not in team chats. Are we blessed or blind?

If I have been able to help feel free to add to my reputation +/- below - thanks!

Already tried that... no doubt there are bad encodes out there and they play back bad on any player... but the average blockbuster/series etc tend to have good sync.
So... i've tried this many many times and when XBMC fails to sync I can start the same file in another player and it plays back with perfect sync. No other changes than just closing xbmc and opening MPC or some other player...
I've also basicaly replicated the hardware setup of one of the devs and no doubt the hardware is good and with the AE branch there is much less trouble than it was with EDEN, but... it's still there in a much bigger degree than on any other player i've tested.
I've tuned my system to compensate for TV-lag etc, but XBMC still goes in and out of sync.
And yes... as someone else said... it has been like this for a couple of years now, but hey... that doesn't mean we should stop crossing fingers and hoping;p

Here's something to try - just for the hell of it and it may just give DDDamian and the others something to ponder. Try a file without vsynch enabled. I seem to remember that turning it off brought things back to sync when I was having issues (pre AE). Makes the video unwatchable but perhaps something that if confirmed by someone else could be looked at by the devs.

I'm into video encoding, and creating video backups from my BD/DVD collection so i'm well placed to carry out tests as i also still see the 250ms delay on AE builds. I did lots of testing a while back, however would like to recheck some stuff. Leave it with me, i'll do that tonight and update on it then.
If memory serves me right, basically, i saw differences in sync based on av container. For example, an M2TS file from a BD folder backup was fine on sync, however when the audio/video from that same BD folder was muxed to MKV using either MakeMKV or MKVMerge, sync was out.
If i give the MKV a 250ms audio delay (during mux using MKVMerge), then sync was good at 24p. Can't remember the sync issue when audio was decoded by XBMC to lpcm.
Now, as an interesting (and totally unrelated!) side note... not sure how audio is handled when played at 60Hz using 2:3 pull down, however even with that 250ms audio delay muxed into the MKV file, XBMC played it in perfect sync at 60Hz! I was expecting it to be out by 250ms!! Anyway...
Another interesting (and very very relevant) side note... again if memory serves me right, i saw the exact same sync problem using mpc-hc and refresh rate switching.
As well as testing sync on decoded audio, i'll also test sync with display set manually to 24Hz, and with refresh rate switching disabled.
Anyway, i'll get testing again tonight to confirm, and post an update. What i'd like to know is what container people are using when they see the sync issue? Is it only MKV?
Cheers
I believe providing files for devs to test with won't be of any help. I've already covered that with dddamian, and on a file i had sync issues with, he didn't.
Cheers
