You might want to try reading the relevant post when someone takes the time to provide you with information, just saying.

From the info you give above for container/codecs we're looking for any specific containers/video formats/audio formats which seem to stand out. Is it across the board for you? All files? Several other users seem to notice most on DTS for example.
For deviation are you seeing a steady state? Audio leading or lagging or random?
Sure you have, but have you tried without Adjust Refresh to Display?
Do you find any advantage to software decoding of the audio and then skip/duping audio packets?

Is this then a correct summary? If in doubt then say, as we're looking only for definitive answers here:
OS Version:win 7 64bit
GPU: GT430 Nvidia
Video Driver:8.17.12.9053
Soundcard:Realtek on board High Definition
Receiverioneer VSX3300
Audio Drivers:6.0.1.6343
XBMC Build:Eden Beta 1
XBMC Settingsync to display drop/dupe audio, adjust refresh to display
Container/codecs: AVI / XVid / ac3 and AAC (DTS not tested), SD okay, h264 okay
Muxer Version: unknown
Deviation: 235-250ms audio leading <<------ are you sure??
Quote:The way I've encoded videos over the years has changed, and I've found that the older ones (in avi containers encoded as XviD-video and AC3- or MP3-audio) seem to have a persistent issue with the audio being about 0.150 seconds behind the video. The more recently encoded videos (in m4v containers encoded as AVC1-video and AAC-audio) all play fine with perfect sync.

Out of interest, i downloaded Eden and tested sync again at 24p. Well, compared to AE, it was a mile out. So i dug out a BD disc (Lord of the Rings: Fellowship of the Ring) and sync checked with my DB player. Guess what... that sync matched XBMC AE's sync perfectly. LOTRFOTR was one of the vids that always looked out of sync to me on my HTPC, so was always my main test clip. Guess it must be something with the sync on that DB that looks funny to my eyes.
So i stopped being a dushbag, and started checking alot more vids. I'm very happy to report sync is actually good. Not sure what the hell i was seeing or thinking previously... time for an eye test i think.
Really sorry guys for the red herring. DDDamian... sorry buddy. Looks like you have been right on the money with Windows AE and sync. One less person to worry about anyway!!
Cheers

I also got the same issue with mpc-hc and even my boxee box and ps3. Something about 24p through my avr causes delay.
