[via freeware junkie
has created a great freeware program called Zorro
which hides all the annoying Java and ads surrounding the TV stream.
It's very simple to use. Open it up, size the window to your preference, then hit ESC on your keyboard to black out anything that falls outside of the Zorro window frame.
Zorro features a number of options (I didn't think that I needed anything else!) that can enhance online viewing a bit more, such as making Zorro always appear on top, disabling the screen saver (this is good), activation hotkey, and more.
