Edd,
Could you post (or privately email) your xorg.conf and X.org.log
I don't know a thing about S-Video and have never heard of "Scart"
before, but we might be able to get the TV Out (Composite Video)
working on that card with the default driver.
At one point in time, the TV Out on nVidia cards was handled by a
separate chipset (brooktree/conexant/philips/?) but I doubt that is the
case on GeForce4mx and newer cards. None the less, the trick with cards
that have multiple outputs is making sure you're talking to the right
output. The nv(4) driver will try to auto-detect if an output device is
connected (monitor/TV/?) but it may not get it right and may default to
the wrong output.
There are two things you can try:
1.) Force access to the TV Out interface through the BusID
(see xorg.conf(5))
BusID "PCI:1:0:0"
# or
BusID "PCI:2:0:0"
2.) Force access to the TV Out interface through CrtcNumber
(see nv(4))
Option "CrtcNumber" "integer"
You can often coerce (force) video cards with multiple outputs to play
nicely even when they are such total garbage that the vendor (nVidia)
is afraid to provide specifications for them.
There is one issue I see that might be a problem, namely NTSC versus PAL
but a lot of TV sets these days can accept either, so we might get
lucky. If not, the PAL modelines you posted look reasonable.
Kind Regards,
JCR
