Is there a difference between H.264 Mpeg-4/AVC and H.264 Mkv? Both played smooth on my Lenovo Q180 in XBMC Eden. After I upgraded to Pre-Frodo alpha 5, H.264 Mpeg-4/AVC movies now stutter/lag on playback. Mkv files that are encoded H.264 continue to play smoothly. I added the advanced setting skiploopfilter, and set it to the max (48), but it only helped a little. I've also tried every combination of XBMC and AMD CCC settings, to no avail.

Any ideas? I'll post a log file when I get a chance. Thanks!

Ok, here's the log file: http://pastebin.com/9zuaNPAW

And here's my system:
Lenovo Q180
Intel Atom D2700 dual-core processor
Windows 7 Home Premium, SP1
AMD Radeon HD 6400 512 MB, CCC version 12.8
Realtek HD Audio driver ver. 6.0.1.6531
4GB DDR3 memory

I should also mention...1080p mkv files play fine, but all of my 720p mp4 files stutter in Frodo alpha 5.

Forgot to say that the problem movies play fine on the Lenovo Q180 using the VLC media player.

In the audio setup in XBMC, I have the audio output device and the passthrough device set to WASAPI: SP-DIF - Realtek Digital Output (Realtek High Definition Audio)

Solved by disabling the XBMC settings for DTS and Dolby Digital capable receivers. http://forum.xbmc.org/showthread.php?tid=80247&page=36

I had the same issue with stuttering video playback after upgrading from Alpha4 to Alpha5 and posted what worked for me in another related thread.

Issue fixed - try a nightly build.
