Hi guys, I'm new here and I desperately need your help! :cheers: My HTPC is built with an Asrock 939A790GMH, CPU is an X2 4400+, GPU is the integrated HD3300 (using last 13.9 legacy) and OS is Windows 7 x64. I usually use Kodi to watch movies and listen music, and PowerDVD 14 to watch blurays. Never had a problem before. Recently a friend of mine gave me The Matrix Trilogy blurays. When I tried to watch the first one, it was quite impossible. The video flicks more or less every 5/10 seconds, resulting very annoying. I have no pixellation and no corruption, simply the video has quickly "flash" (sorry guys I'm not english and I don't know how describe it) like frames distortions, they last some milliseconds, than video returns normal, and after some seconds again the problem. I was surprised, because I never had that problem. Using BD Info, I saw that it was a VC-1 bluray, while all my other blurays are AVC. To be sure, I played that bluray on another system with an nVidia card and it played perfectly, so not a defective disc. I borrowed another VC-1 movie from my friend, same problem. So it's defenitely a bug with VC-1 codec. In PowerDVD, changing hardware/software acceleration didn't change anything. I installed the trial of WinDVD Pro 11, and I got the same behaviour. So, not a PowerDVD related problem. I installed the trial of AnyDVD and tried to play the movie within Kodi, and I discovered that with DXVA2 enabled I have the same bug, while with DXVA2 disabled the problem disappear, but the system has great difficulty to play it without hardware acceleration. Tried also with MPC-HC enabling/disabling DXVA2 acceleration, same behaviour. So, it's for sure a problem with DXVA2 acceleration and AMD drivers. So, I tried differents drivers: 9.4, 11.12, those in motherboard CD, 13.1, Dellon modded, 14.12 modded with Flem. No succes at all! Rather, with oldest drivers I got also green pixellation. So guys, someone can help me to fix this really annoying problem?! I'm scared there will be no fix for this, I think I tried everything.... Sorry for the long post, but I wanted to share all my tests. Thanks in advance!
