How do I get TV out working on an ATI X800 GTO²?

Question

Is there any way to make my graphics card (ATI x800) work with tvout? I know there are no proprietary drivers for this card only the opensource ones. It uses this cable for video out:

Personally I use the yellow RCA for tvout (in windows). I hope there is a way to work it out because it's a really important feature for me and one of the only reasons I boot windows.

Thanks ahead!

From the X.Org Wiki:

You can enable TV-Out either dynamically (by issuing commands to the running X server) or statically (through the xorg.config file, before starting the X server). For testing, the dynamic method is probably easier.

Enabling TV-Out Dynamically

TV-out may be enabled by using a recent driver and xrandr utility:

xrandr --addmode S-video 800x600

xrandr --output S-video --mode 800x600

xrandr --output S-video --set tv_standard ntsc

Enabling TV-Out Statically

Several options need to be specified. See the radeon(4) manpage for a description. In particular, you must set "TVStandard" to match your flavour of video.

This recipe is not definitive, but it has worked.

In the "Device" section:

   Driver  "radeon"
   Option "TVDACLoadDetect" "TRUE"
   Option "TVStandard" "ntsc"
   Option "monitor-S-video" "TV-monitor"

In the "Monitor" Section:

   Option  "PreferredMode"  "800x600"

In the "Screen" section:

    DefaultDepth  24
    SubSection "Display"
            Depth          24
            Modes         "800x600"
    EndSubSection
