Hi All,

this is my first post so i'm sorry if i miss some information! I'm having some issues displaying full screen videos. I've installed mediaportal and i cannot manage to have fullscreen DXVA accelerated video, the screen remains blank and is possible to hear audio only. If i turn in preview mode is visible again! This seems to happens only with h264 videos which are dvxa accelerated on the other types i don't have any problem. I've tried to change also the codec using the cyberlink 8 but same problem. After lot of tries I've discovered that changing the quartz.dll from the 6.5.2600.5512 to the 6.05.1.902 the problem is gone, but all the new MP versions warn me that this .dll is bugged!
Does anybody here have some suggestion or solution?

Thank you very much!
