unable to get PAL signal on TV-out

[Belegdol]

Hi,

I am trying hard to get the TV-out to output a PAL signal. I did put the appropriate option into the xorg.conf file, but no matter which PAL variant I choose, when I enable the TV via nvidia-settings, the signal is NTSC. I'm doing this via an s-video cable. The GPU I have on this box is a FX 5700, and it is running the 173.14.15 drivers. The machine is running Fedora 9. I Also tried creating more complex xorg.conf with a screen section, but it had no effect. The one I'm using currently looks the following:

# Xorg configuration created by livna-config-display

Section "Files"
	ModulePath   "/usr/lib/xorg/modules/extensions/nvidia"
	ModulePath   "/usr/lib/xorg/modules"
EndSection

Section "ServerFlags"
	Option	    "AIGLX" "on"
EndSection

Section "Device"
	Identifier  "Videocard0"
	Driver      "nvidia"
	Option	    "AddARGBGLXVisuals" "True"
	Option	    "TVStandard" "PAL-B"
EndSection

Section "Extensions"
	Option	    "Composite" "Enable"
EndSection

According to the log (attached), the TVStandard option is understood, it just isn't applied. Please advise, as I have no more ideas what to try and the open source drivers do not support tv-out yet (I wouldn't mind losing the acceleration since the GPU is ancient anyway). Thanks in advance.
