Not knowing your expertise with computers, I will keep this general. If you need more details, reply and I'll be more specific.
If the 8500 is like the 7500, you need to get to properties (right mouse click on the desktop) and click the Display Tab. Select the TV. There should be a check box to check - something like 'extend my desktop to the second monitor'. Check it. You may have to restart your computer.
Open Hoster. While playing a song, you probably have a little TV window you can move around on the screen. Grab it with the curser and drag it off the screen to the other screen. If this works for you, you can toggle the screen back to your computer screen by double clicking you mouse on the TV screen.
Hope this helps.
