This method works quite well, and is easy to set up. Connect the composite out (so only possible on A1200 obvious) to the TV card, edit the Voodoo monitor driver and change the DISPLAYCHAIN tooltype to the opposite of what it is now. Install TV card software (SuperTV is very good), launch the program, switch to composite input and launch your WHDLoad game and it should display in the TV screen on top of your Voodoo screen.
