Hello, I am a new XBMC user converting from Popcorn Hour and I have to say I am already in love. I went out an built a nice machine (specs below) and it has been playing all of my files very smoothly. I only use 1080p content except for a very small set of TV shows, and it is doing a great job. There is just one slight issue that is not a huge deal but is bothersome. Every time I resume a movie and even occasionally on starting fresh I experience a very brief (2 secs) of green pixels from what I'm assuming is DXVA. I have DXVA turned on and I have GPU acceleration turned on for the graphics card. That is really all I am using, I don't have codecs installed and I'm using the stock player. Is this something that can be fixed, perhaps with a codec. I really don't like installing codec packs, etc. but if it will fix the problem I'm game. It is particularly annoying when using PseudoTV - which I absolutely love btw. Any help would be greatly appreciated!
Specs:
AMD A8 3870k with AMD Radeon 6550 HD Graphics
ASRock MB-A75M
G.Skill Ripjaws 4GB
Silverstone ML03B Case
Seasonic SS-400ET
I will also be upgrading the heatsink in the near future once I find one to fit the case, the stock one for the A8 is slightly noisy IMO.

If you are using the default XBMC built in player, installing codecs are a waste of time. XBMC does not use them. It has everything it needs built in. You only need codecs for some external players.
Best thing it to check your AMD video drviers and XBMC playback settings and find the best settings for them. Search thru the forums. There are many threads about various things AMD/ATI drivers and XBMC playback. You may find a thread relevant to your query.

Thanks for the response! I installed the dsplayer XBMC version and I have DXVA turned off and I do not get the green artifacts. I am going to test some files over the next week or so to see how playback is with DXVA turned off. Is there really any disadvantage to having it turned of in XBMC? I still will have GPU acceleration turned on in my Graphics settings.

Sorry, I don't use AMD GPUs, so there isn't much more I can suggest. Maybe Bluray will pop into this thread. He seems to be quite familiar with AMDs drivers and settings.

Overall temp is around 40-50C, but if could very well be a RAM issue as my RAM is not on that list. I think I have some other sticks laying around so I will try them when I get home from work. Thanks for the suggestions, hopefully I can post back here this evening to say everything is working 100%.

@tman12-
You can try the one stick of RAM trick first. If it doesn't work, you can try the CPU Vcore below.....
The temperature is fine. Sometime, the CPU Vcore voltage can be set too high by AsRock default settings too. If it set too high, you can try to set it to 1.225v in bios. If it is too high, CPU might not be stable.......
Rule of thumb- you need to try one thing at a time. If it doesn't change anything, you can set it back to the original setting and move on......
If all the above doesn't work, you might want to chat with AMD tech.....

So I tried using one stick of RAM - one and then the other, and tried a different set of RAM that I had and still brief green when DXVA is chosen. I also set CPU to 1.220v in the bios and still didn't work. I think I'm just going to go with Pixel shaders for render method and leave everything else turned off. I get my best performance that way with occasional clear artifacts (not many) but no green artifacts at all. Just a shame because I really thought this build was going to be a beast and I was looking forward to being able to smoothly change channels in PseudoTV and no issues at all during resume and even on start but I'm fairly pleased. It just sucks to go from a great player with lousy interface (Popcorn) to a great interface but just OK player.

I also have the same problem.
It only occurs with XBMC.
However, after I disabled the hardware acceleration, the problem went away.
My chipset is Intel (onboard video).
