This HOWTO should help you enable TV-Out support on your ATI Radeon or ATI Rage based ThinkPad.

This page is not applicable to recent ATI Radeon Mobility chips. See ATI Mobility Radeon X300 for a discussion.
If your using a distribution with KMS (Kernel Mode Setting), such as Fedora 11 then you will not have S-video support. This is a known issue. The only workaround is by booting with the nomodeset kernel option.

Using Xrandr

To use the TVout on Radeon 7500 type following:

$  xrandr --output S-video --set load_detection 1 
$  xrandr --addmode S-video 800x600 
$  xrandr --output S-video --mode 800x600 

And set mode PAL or NTSC with:

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

If you want to use XVideo overlay on TV, try following command:

$  xvattr -a XV_CRTC -v 1
