While the Catalyst Control Center software gives you additional parameters to tweak the display, I've been able to avoid using it. I use the Advanced Settings under the Windows Control Panel, Display, Screen Resolution to select the necessary screen resolution (720 by 576) and refresh rate (25Hz or maybe 29Hz). Depending on the version of the ATI Radeon video driver you have installed, this refresh rate may not be available. I think Catalyst v10-8 (driver version 8.632.0.0 dated 7/2/2009) was the last time they supported it.
I've also found that if you are knowledgeable, careful, or don't care about the potential for damaging your machine, ATI Tray Tools (ATT) by Ray Adams (http://www.guru3d.com/article/ati-tray-tools-/) will work in place of the Catalyst Control Center for tweaking the TV output options. Be sure to read all the documentation and warnings you can find and be prepared to experiment. To enable the TV out options, install ATT and add "hide_display=0" (without quotes) to the atitray.ini file located at C:\Program Files (x86)\Ray Adams\ATI Tray Tools\
By the way, I was able to correct the checkerboard and color problems I was having by connecting an S-video to RCA adapter to the S-video output of the VGA adapter like this:
Computer (VGA output) -> VGA to S-Video adapter -> S-Video to RCA adapter -> TV (RCA video input)
I suspect the 1st adapter is actually miswired and the second adapter happens to correct it. The second adapter came as an accessory with an Asus motherboard, but it looks just like the "StarTech.com S-Video-to-RCA Composite Video Adapter F/M" at http://www.amazon.com/StarTech-com-S-Video-Composite-Adapter-inches/dp/B0009E...
Hope this helps.
