Windows 7: Connecting Radeon 4890 to older CRT TV

Hello. I am trying to connect my radeon 4890 (on a windows 7 ultimate 64 system) to an older CRT big screen TV. I am using the s-video on the card to component on the TV.

In catalyst control center I can see my monitor and TV as displays but not sure what to do from there. Do I click on the TV icon to extend the main display to it or do I click on the monitor icon to extend the display to the TV??

My guess is the TV which I have tried. But it takes about 30 seconds or so for anything to show on the TV and when it does its like the vertical hold is out of whack (refresh rate?)

Control center says I only have one primary display - no secondary display shows even though the TV icon is there.

Do I need to set the main display to 640x480 60hz?? I know that component can go to 800x600 but as my TV is only 480i I don't think I can use that resolution.

I just want to expirament with this for now and use it for the occasional TV show online thats about it.

ALSO is there a way I can set the main monitor to run at a mid-level resolution (such as 1280 x 1024) and set the (secondary) TV output to run at 640x480 and keep those settings??

Any assistance you can provide would be much appreciated.
