If you're using Windows Vista or later, and have Aero (DWM) enabled, then you have the option of enabling this "Cursor-based Video FX" option in order to see a view from around the cursor in the target window, while Repeater is enabled. If you are on Windows XP or earlier, or have Aero (DWM) disabled, then this option will appear to do nothing.

OK TY SO MUCH
