the only thing out of sync for me is xvid type movies at 24fps. h264 and x264 mkv etc are perfect. just frustrating to have to avoid xvid files. even when I delay them, its just not quite right.

gt430 nvidia card. i use the auto refresh rate option and sync video to display using video clock.

I think I have solved the problem but need more testing to make sure.
When I reset the pc fully I don't get the problem I think it has somthing to do with xbmc and comming out of sleep mode as it seems to be perfect on a full reset.
Things I am going to try is
Shut down xbmc to desktop and reload and do not reset the computer
Change the order of how I power the amp on and changing the channel to the htpc to see if it's a hdmi edid problem.
I think it's a sleep mode problem to be honest because somtimes I get stuttering video and a reset of the pc or closing down xbmc and reloading it solves it and seems to be the same for my sync problems.
I have seen many posts on hear about sleep mode braking xbmc and also seen a ticket for it but I don't know if this is been sorted as it's been there for a long time and no info has been given on that problem but hope it will be fixed in xbmc 11 which I hope it does.
Wounder if changing sleep mode to hibernate will fix the problem as that shuts the whole computer down fully but means I have to wait for windows and xbmc to load.
A few things to try but I do think it's a sleep problem with xbmc it just does not work to well with it at all

Nope certainly not my issue - my PC is never on sleep/hibernate or whatever and I still get it.

yep me too, I bring the computer downstairs to watch movies, (yes I know I'm insane) so its never sleeping or hibernating.
same problem always with xvid type movies. I try not to use that type as the audio is never quite right. h264 movies work flawlessly. i'm about to see if I can find a converter to convert the stuff to h264 although probably not worth the hassle.

I have done some more testing and for me i think what is causing my problem is that I have 2 profiles.
The first profile is setup for 5.1 amp and the 2nd profile is setup for 2.0 tv stereo. An I think when I switch profiles it might cause this problem as I have left in inthe 5.1 amp profile for a week and have had no problems.
So it's either a xbmc problem with profiles when changing audio settings or somthing to do with the hdmi handshake problem.
The next test is to use optical for 5.1 and then put the hdmi into the tv and switch profiles to see if it happens again if it does this is a xbmc problem if not it will be somthing to do with the hdmi.
I know there is a new Audio engine comming to xbmc and has been greatly updated so I am goingto wait on that release before I do anything as I hope that might fix the problems and I hope it supports hdmi edid as of now it does not seem to as if it did I would not need 2 profiles for different sound options as when i passthrough audio to the amp to the tv when the amp is in standby it still passes 5.1 to the tv which it does not support and I get no sound but on my blu ray player it auto detects this and switches
So will see what happens and also it supported the new hd audios But I am still trying to narrow this problem down.

i run optical out for 5.1, I don't do anything with profiles and I have this problem.

Yeah me too. I run optical all the time as i don't have HDMI connections on my AV receiver. I was actually thinking of getting a receiver with HDMI to try and solve. LOL.
I also sometime find a reboot fixes the sync probs. Sometimes not. I am using MPC-HC, however I think this problem is very similar.
