Recently I had been unable to view µTube videos on full screen and I'd been at loss as to why.  It turns out the cause was the new version of flash, 9, which for some reason would play the standard µTube size fine but fail to properly play on full screen.  I realize that most people would prefer to watch that standard size since uTube is greatly lacking in video quality and it appears decent standard player.  However, I discovered via a helpful message board that all I needed to do was right click on the player, go to settings and uncheck the hardware acceleration.  Now I'm free to properly watch poor quality videos on the big screen.
