I will apologize up front that I am not a newbie to using XBMC but I am a newbie to asking for help. I am not a computer expert by a long shot. I have been using XBMC on my Win 7 (64 bit) htpc without much problem for awhile. Recently, after a display driver update (and maybe an auto Windows update), my blu ray rips are now stuttering very badly. Following the display driver update, I tried to roll back the driver, with no luck. I made no changes to any audio settings on either the htpc or in XBMC. Also, when I play the blu ray rips using VLC on the htpc, they play fine.

My hardware is:

Zotac ZBox AD04
AMD E450 with Radeon 6320
8 GB Ram

HTPC runs through my Onkyo receiver and into a Panasonic 1080p TV.

I see from other posts that I should post a log. I have no idea if I did it right, but here's the link:

Thanks for any help.

(UPDATE)
As I continued to search in this forum for possible fixes, I noticed that some were changing their audio output in XBMC to WASAPI instead of Direct Sound. I switched to WASAPI, and my 1080 movies now work. I don't know why, but I'm not complaining.

It's also very worth while checking out this post: http://forum.xbmc.org/showthread.php?tid=146911

Also disabling ALL video quality rubbish within Catalyst will greatly improve performance.

Thanks much, Piers. With all my searching, I don't know how I missed that thread. I appreciate your help.

You're welcome. Working out the cause of video stutter can be quite frustrating but that thread has helped many.

Because DirectSound is usually used for TV speakers, and WASAPI is used for bitstreaming codec to capable receive. Since you have Onkyo, you should be using WASAPI for bitstreaming codec to Onkyo for decoding....if you need more ideas to insure smooth playback using your AMD iGPU, you can check my post #2...
