I'm a total noob guys, so please bear with me. I will try to make it as succinct as possible. Whenever I try to play some of my videos(not happening with all), regardless of the video format, there is a horizontal line of disturbance on the top of the video, usually 2-3 cm down from the top. Well, it is only noticeable when the video is in full screen mood and I have no idea how to describe the problem. I hope it is something that can be fixed easily. I googled it without luck. Is there any solution to this? BTW I am running Ubuntu 11.10 64-bit on Dell Inspiron N5050.
If you are using the proprietary AMD video drivers (fglrx), then this is a well known problem. There is a setting in the AMD Catalyst Control Center that is supposed to fix this (I think it's called tear free playback or something like this). Another solution, which will probably work, is to uninstall fglrx and use the open source radeon driver instead (which in turn has its own problems like bad performance in games and no audio when using hdmi).
