I am using an AIW Radeon and get black at top and bottom of screen. Have tried everything and here is what I have found out. Capture has NOTHING to do with my problem. As soon as I turn on the TV under the prefs for my Radeon dsiplay (with or without the monitor turnrd on), I get the black at top and bottom of BOTH screens, Again, this happens even before I do anything with ANY videoeding program. Any advice?
