General ATI TV-out problem with PAL B/G?

Dear Andreas,
    If you use the command line, the information will be lost if you quit X. If you want to save these changes, you must write them as options in xorg.conf manually. 
Best wishes,

I'm using version 6.10.0 which I compiled from the Debian experimental
package for my Debian lenny system.

The commands I use for turning the S-video output on are:

xrandr --output S-video --set load_detection 1
xrandr --addmode S-video 800x600
xrandr --output S-video --set tv_standard pal
xrandr --output S-video --mode 800x600 --right-of LVDS

After doing that, xrandr says:

Screen 0: minimum 320 x 200, current 2080 x 800, maximum 2080 x 800
VGA-0 disconnected (normal left inverted right x axis y axis)
LVDS connected 1280x800+0+0 (normal left inverted right x axis y axis)
0mm x 0mm 1280x800       60.1*+   60.0  
   1280x768       60.0  
   1024x768       60.0  
   800x600        60.3  
   640x480        59.9  
S-video connected 800x600+1280+0 (normal left inverted right x axis y
axis) 0mm x 0mm 800x600        59.9*+   60.3

The relevant lspci-line is:
01:00.0 VGA compatible controller: ATI Technologies Inc RV350 [Mobility
Radeon 9600 M10]

I pasted the Xorg.log to The steps I did
were: Turn TV on with the commands above, switch to VT and again the
commands from above.

Best regards,
Andreas Juch
