When I run TV-Tool it takes over my TV straight away. Before it takes over my TV is setup to play an offscreen portion of my desktop so I can drag windows and programs into it which will only be displayed on the TV while the computer still runs the normal windows display on my monitor. When TV-Tool is started it takes control of my TV and resets it. Although the option for taking off Macrovision is good, I was wondering if there was anyway to stop TV-Tool taking control of your TV and leaving it how it is. But with the added bonus u can watch Macrovision protected DVD's.
