Thanks, guys.

My PC monitor is plugged into the Radon X1300 so I'm sure the on-board video is disabled, no?

I have already been to the WEETHET site. They talk about the Radeon 9000 (as does your link, fink) but the screens it shows are not the ones I get with the X1300.

The links to SVIDEO.COM tell me nothing except how to connect the cables. The flash video there talks about dragging programs to the second screen. I don't know what they're talking about.

The X1300 has 3 outputs ... a VGA, S-VIDEO and a DVI. So how do I know this second monitor is not the DVI? If I do transfer the video to the DVI, I will have no way of seeing it and therefore no way of moving the video back to my VGA monitor.

Maybe I wasn't clear in my initial post ...

I am downloading AVI and MOV video podcasts and want to watch them on the TV rather than the PC monitor. I don't want to set up my TV as my PC monitor
