This has been driving me nuts from day one of XBMC, starting with Frodo & continuing thru Gotham 13.0. After a lot of experimentation, I finally found a combo that seems to work for blu ray MKV 24p playback & I'd thought I'd pass it on.
Windows 7, Intel HD graphics 9.17.10.2932, HDMI out to Denon 3310 receiver, Sharp 1080p 70"
Display resolution is set to 1920x1080, 59.97 Hz
Make sure you are NOT using a Windows AERO theme desktop.
XBMC settings:
Vertical sync =off
Use windowed fullscreen instead of true fullscreen
audio set up:
audio output device = direct sound HDMI
wasapi HDMI passthru
video playback settings:
adjust display to match video refresh rate= on stop /start, delay = 3 seconds (this is because it takes my display a few seconds to display after a resolution/ refresh rate change)
sync playback to display=on
sync method= audio clock
render method= dxva, hardware accelerated
Smooth playback on 24p material, 0% errors after about 10 seconds or so of playback, on True HD or DTS master audio HD soundracks.
Vertical sync= on also produces smooth playback with good audio sync during movie & after chapter changes. In both instances, audio errors zero out in about 8-10 seconds & maintain a solid zero.
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
True fullscreen, vertical sync =on, temporal audio sync issues in True HD, waaaayy off with DTS MA, both on start up & chapter changes.
True fullscreen, vertical sync = off, smooth playback but audio takes longer to lock in on start up & after chapter change, both audio formats. Doesn't seem as locked in to me.
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
If an AERO desktop is used, that's when things go wacky.
Same windowed settings as above, playing a DTS MA movie like ALIENS, frame rate is reduced drastically. Same reults with True HD like Dark Knight.
Enabling vertical sync yields same results with True HD or DTS MA.
Using True fullscreen, vertical sync on, True HD & DTS MA both lose sync after chapter change, major errors
True fullscreen, vertical sync off= stuttering playback, audio errors jumping around with True HD. loss of audio sync after chapter changes using DTS MA.
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
In summary, on my system, I get the best results playing in a fullscreen window as opposed to true fullscreen, and Windows AERO desktop should be avoided.
