May I ask what gfx card you are using for testing playing YouTube videos...?
On my X5000 equipped with Radeon X1950 Pro often the lower third of the videos are black and I have to try with the mouse pointer to get he full screen. In general, 'working' with the video (full screen, stop, play, changing sound volume etc) is a little tough...
Any options to make this more smooth on my side?
Thanks!
