Here's my relevant part of the xorg.conf (it works), different card,
most likely same driver though. This also allows beryl to work.

Identifier "GForce 6200"
Driver "nvidia"
Option "IgnoreDisplayDevices" "TV"
Option "Coolbits" "1"
Option "RenderAccel" "1"
Option "AllowGLXWithComposite" "1"
Option "RandRRotation" "1"
Option "AddARGBGLXVisuals" "1"
Option "DisableGLXRootClipping" "1"
Option "TripleBuffer" "1"
Option "UseEDID" "1"
Option "UseEdidFreqs" "1"
Option "DynamicTwinView" "0"
BusID "PCI:1:0:0"
VideoRam 131768
Option "NoLogo" "TRUE"
Option "NvAGP" "2"
Option "DigitalVibrance" "0"
Option "TransparentIndex" "0"
Option "CursorShadowAlpha" "64"
Option "CursorShadowXOffse" "4"
Option "Twinview" "1"
Option "TwinViewOrientation" "clone"
Option "SecondMonitorHorizSync" "30-50"
Option "SecondMonitorVertRefresh" "60"
Option "Xinerama" "0"
Option "MetaModes" "1280x1024 , 1024x768"
Option "ConnectedMonitor" "CRT , TV"
Option "UseInit10Module" "true"

Quite a bit of difference I would say. Keep in mind the NvAGP may not
be appropriate for your card, if in doubt, set that to 0.

The setup is quite different, but this "Device" works for me.

Section "Device"
Identifier "nVidia Corporation NV17 [GeForce4 440 Go]"
Driver "nvidia"
BusID "PCI:1:0:0"
Option "UseFBDev" "true"
# TV Out Setup
Option "TVStandard" "NTSC"
Option "TVOutFormat" "SVIDEO"
Option "TVOverScan" "0.6"
Option "ConnectedMonitor" "TV"
EndSection

Could nvtv have problems with my card just because nvtv is out-of-date? I
checked out the sourceforge site and there's no real activity to speak of there,
for quite a while now.

Are you sure you can feed S-Video to that input? On my TV there are two
SCARTs in the back but only one of them works with S-Video and I also
have to switch with the remote to SVHS2 and not AV2 (which only gives
BW). Read your TV's manual carefully. BTW, mine is a Daewoo.

HTH,
Andrei
