brief green pixelation during resume

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.

Don't blame the player for hardware/driver issues but I do understand your frustration. I've never been 100% pleased with an AMD/ATI GPU so for years I've avoided them. That is jut compounded by the many reports of video playback issues with AMD/ATI reported in these forums over the years.

If I were stuck with this card, I would disable everything possible in the drivers. Such as that steady video setting and the GPU scaling and ITC processing. Does AMD/ATI still allow installing basic drivers without all that extra crap?

@tman12-

As I mentioned, it is time to chat with AMD technical staff. They're your friend and they should be able to help you on it.........

I found this thread, and maybe you can ask those guys- Fix for artifacts with ATI cards and DXVA2 decoding

Funny you should mention AMD technical staff, just got off the phone with them... extremely unhelpful. They had no idea what XBMC was and they asked who the company was. Then they told me that I would either need to contact DirectX or XBMC because it is an application setting. I can't say I really blame them, they don't know what the limitations are of XBMC or what settings to use.

Well when the files playback fine on VLC and Dsplayer its kind of hard not to suspect that it is a player issue. I think I'm going to try the patch suggested by bluray first and then maybe look into the card settings a little more even though I think I've tried every setting possible.

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).

A little update, and more sad news. I went out and (foolishly) bought a graphics card expecting my green pixel problem to go away. I purchased the HIS Radeon HD 6670 1GB and put my build into a different case I had lying around intending to upgrade the ML03B if my tests worked. I put in the card and installed Win7 64 then the 12.3 Catalyst drivers - making sure crossfire was enabled for maximum performance. I installed Eden and went to play several files that were troublesome and there it was again, that evil green macroblocking with DXVA2 turned on. With DXVA2 off and just DXVA on I'm not getting the green pixels but I am still getting some pixelation/macroblocking (greyish). I thought I was building a powerful enough HTPC to have no worries about DXVA2, apparently I was mistaken. The frustrating thing is that I do get the best performance with DXVA/DXVA2 turned on aside from the brief pixelation during skips and resume and I really want to use this setting because of the great CPU levels and for the fact that I BOUGHT THE HARDWARE FOR DXVA! I feel like digging a hole and burying the damn build.

Also let me just make a note, ALL of my media are 1:1 bluray ripped to mkv using makemkv. Too often I see comments on here from guys that are not using 1:1 rips talking about everything working perfectly. I'm sure it is working perfectly when you're playing 12GB files at low bitrates, but that is not the purpose of my home theater or the equipment I use. Not trying to rip on those users at all and each person has their own standards, just saying the level of hardware/decoding is different for small vs large files.

Sorry you are having such problems. Can you return the graphics card you bought and try a nVidia card? You went from AMD to AMD. Chances are the drivers are not that much different. If there is a problem with the drivers you will still have them. You could provide a small sample file that has the issues you are dealing with. Then we can test it out on different hardware.

Do you really think it would be an AMD issue? I only ask because these files play great in VLC even with doing some crazy skipping forward and backwards - I tried to replicate what I was seeing and I couldn't. The only conclusion I can think of at this point would be that it has something to do with the xbmc player/codec itself. I can try to create a sample later this evening, if you happen to have a bluray of a bugs life laying around you could test that lol. My go to files for testing are Cast Away due to a very high bitrate, A Bug's Life in the first 3 seconds when the disney pixar logo is loading (basically the file I go to because it is an immediate indicator that I still have green pixelation), Beauty and the Beast also gives me some trouble when skipping around. The weird thing is that Avatar has no problems though - even skipping through. All of these files are 1:1 bluray MKV from makemkv and are h.264. I tried digging into the files using MediaInfo to see if I could spot any differences. It's hard to really tell because there are a lot of different things being reported, but I am curious about the Reframes which are different or not present in some of the files. Thanks for your response!

Sorry, I do not have any of those laying around. If you could make a test file and confirm it has the issue then share it, I'd be happy to test it on 2 different systems. One with nVidia and one with Intel HD3000.

I do find it odd you do not have those issue in VLC. That does tend to make one think it is truly XBMC related. If you get that sample file we can test it for sure.

Are those 1:1 rips in 10bit or 8bit color? XBMC does not directly support 10bit color yet.

@tman-
Have you try different Pixel Format in AMD CCC as shown below.......
