[QUOTE="meierk, post: 320060, member: 68720"] After a lot of reading over the past week I unhappy to report that I am more confused than ever and am questioning everything I thought I knew. I built my system based on the 780g chipset for hard acceleration and the AMD 4850e for low power consumption believing that I had the best combination for the least cost..... maybe not the case. I have a problem with a few 1920x1080 MKV files where the image starts to break up after a minute or so of viewing and eventually results in either a complete freeze or my HTPC simple powers off if I don't stop the player in time. I tried SAF last night with the Catalyst 8.5, but the results were the same. So after trying PowerDVD, CoreAVC, ffshow and SAF I decided to try the one thing I should have tried before everything else.... I tried playing the same video using VLC on my main PC. Low and behold, the video does not play properly there as well. CPU was about 70%. I'm now left wondering if the MKV files are just poorly encoded. Can anyone explain to me how I can determine if the MKV files are good? Is there a utility to test the file quality versus the codec? [USER=77164]hoborg[/USER], you said to use Catalyst 8.5 as versions 8.6 - 8.9 have issues with XP. Have you been able to confirm whether the new Catalyst 8.10 is usable? Thx, Kevin [/QUOTE]
