I tried disabling Cinemotion which doesn't do anything. I can't find Motion enhancer anywhere.
Also I can't enable "sync to display" in XBMC as this reduces everything to a crawl when playing videos.

Just to join in this conversation,
I have been using the most up-to-date nightly builds since the Camelot release. The builds within the last few months have been fine regarding a/v sync and the adjust refresh setting.
However, the Beta1 build seems to have brought back some of the issues i used to have back when native dxva2 support was added. Now when i use DXVA2 & adjust refresh i get about a 200ms delay also.

I've been living with a 200ms offset on my Sony LCD since setting up a Karmic/Camelot HTPC earlier this year (currently on Dharma beta2).
Once the offset is set, it runs perfectly for all 24p content.
I've been watching a bit of 50hz content recently and have gotten use to switching between 0 and 200ms audio offset, but thought I'd poke around the forums this evening to see if I could find a more permanent solution.
Turning off Cinema Drive and Motionflow in the Features menu of my LCD seems to have fixed the audio problem for 24p content.
I guess I'll have to weigh up whether sacrificing these video features will make up for no more audio hassles.
Is there anyway of saving specific playback settings for different refresh rates? E.g. Default for all 24p content, that than just default for all videos. I know calibration settings are resolution and refresh rate specific, but are there any advanced settings to tie audio offset to these?

Using a Sony Z5800 LCD and a Nvidia GTX260.
With these settings i have synced playback in all modes.
Using XBMCSetup-Rev33573-dx with ffdshow and haali.
Made Custom Resolution 1920x1080 with these Frequencies:23,24,50,59,60 - 32Bit.
In XBMC Options:
Video-Playback:Adjust Display Refresh Rate to Match Video,Sync Playback to Display,AV-Sync Method=Video Clock(Drop,Dupe Audio)
System-Video Output:Display Mode=Windowed(otherwise wont work),Vertical Blanc Sync=Disabled
Connection from PC to Reciever ist via Optical.
Maybe its usefull for someone,for me these are the only settings where i get synced playback in All Modes.
Edit:Motionflow in Sony Settings is disabled

I can confirm the same issues. Since most of my content is 24p, I've set a delay for all videos. This works well, until I hit a 25fps, or 29.97 fps file. I wound up setting up a command on my remote so I can manually adjust these while I'm watching. It would be nice to be able to adjust the delay based on the fps of the video when using the match refresh rate feature.

Has anyone fixed this issue or know why it occurs.
To confirm, i have disabled all my TVs post processing (100hz) etc but this issue still exists.
Any ideas anyone?

Issue exists on my panasonic pz800 as well with all the features liked cinemotion turned off (not that they were ever turned on). Is there a trac ticket with some info so we know if the devs are looking at it or not.

I had such problems like this before. But not at all now. All I had to do is use turn on Sync Playback to Display with A/V Sync method of Video clock (Drop/Dupe Audio).
Without this option on my audio would run away all the time and my TV is a Kuro (collectors edition )

Should i have to turn on Sync Playback to Display for a 23.976 file playing on my tv after it flicks to 24Hz?
If so thats fine and I can. I do realise that it trys to speed up the audio by 0.01%, but doesn't always get it right for such a small amount.
I thought really that 23.976 was 24p anyway so it should all match up.
