Can't get to the HTPC till Monday but sure its either 22/10 or 23/10 nightly. It is also dropping frames every 8 minutes now (1 every 8mins or so) so the sync doesn't get worse as the film continues.

Excellent video! I've been looking for something like this for a looong time.
I've tested the file on several setups.
PC->Logitech z5500 = Perfect sync
WDTV 3.gen -> Sony Bravia LED = Perfect sync
Popcorn hour C200 -> Panasonic 65VT50 = Perfect sync
HTPC w/MPHC -> NAD M15HD2 -> Panasonic 65VT50 = Perfect sync
HTPC w/XBMC -> NAD M15HD2 -> Panasonic 65VT50 = +/- 85ms ahead. (That means I run with a 85ms audio delay)
And while we're on the subject... Most movies, series etc (mkv container @23,976) runs with good sync @85ms delay.
However most 50/60p material, youtube clips etc has good sync to start with, so I have to re-adjust to 0ms to watch with good sync.
So... still, it seems that XBMC has difficulties with 24p material, just not as much as before...
Only difference seems to be that while it used to delay the sound of 24p material it now puts the audio ahead. At least that's the case for me.
Could also have something to do with how XBMC sends the audio via HDMI? This is not my field of expertise, but logic dictates that digital sources can put the audio ahead because video signals takes more time to process than audio... so the audio ends up ahead. However most new HDMI equipment can auto-adjust lipsync by using some kind of protocol or something via HDMI... Again, not my field of expertise... so maybe XBMC does not send all the info required for the auto-lipsync?
System: XBMC Gotham 13.1, HTPC: AMD 6450 1GB, Intel i5 3470S, 8GB DDR3, ASUS P8H61-M PRO, OCZ SSD Agility 3, NYXboard Hybrid Remote
Surround: NAD M15HD2, NAD M25, B&W 803 Diamond, B&W DB1, B&W HTM4, Pioneer KRP-600A / Panasonic 65VT50

Same here with all the latest nightlies.
With auto refresh rate set to off all is fine, but when it is set to on I have to set the audio to about -200ms for it to appear in sync (for 23,976 content)
One important note though... it's fine while bitstreaming, but has the delay when XBMC has to decode the audio.

It really take so long to fix it. I just tried the mediaportal and with its dynamic refresh rate i dont see this problem, and the bonus for me is it can perfectly play m2ts interleaved files from my cam, which is not possible with xbmc default player. I like xbmc more, but this is may be the reason for me to try something else...

I have had this issue on Windows with all recent nightlies. The lipsync is "ok", but not spot on.
I rolled back to 20120601-cdd9c64-master and here the lipsync is absolutely perfect (with AE and bitstreaming of hd audio).
Something must have happened after this release that screwed things up.
Is this build available for Ubuntu? I am migrating from Windows to Ubuntu but the lipsync issue is forcing me to stay on Windows. Would be fun to see if the Ubuntu package from the same code base is fine too. Anyone know of a place to download old packages?

It's just a hunch, so it may lead to nothing, but...
I personnaly have no issue, so i can't test, but, for those who have issues, have you tested if disabling all DXVA stuff (both in decoding, rendering, etc...) solved/changed anything ? Of course, it makes sense only if CPU is powerfull enough to properly handle video decoding without issue.

Is the sync issue fixed in beta 1 or 2
I am currently running alpha 3 as its the only good one I have found for sync issues

Not for me and the only thing that resolves it is to switch off vertical sync - which of course introduces 'tearing'. And this is the annoying thing it only manifests itself in xbmc - Media Portal, JRiver and using mpc-hc doesn't show any sync issues. Ho Hum.

Since upgrading to Frodo Beta I am having this lip sync issue. However I am not on Windows, I am running XBMCbuntu on a Zotac ID80 machine. I have read through most of this thread, many people have posted didnt types of things they have tried, are there any steps I should take to fix this?
I have tried messing around with matching the refresh rate and video but this seemed to make things work with some tearing.

Same here. I'm using Frodo Beta 2 on Win 8 64bit . I have to use the audio offset setting and adjust it to - 0,175ms. Is it in the plans to be fixed on the next beta?
