TV out is in black and white ?

[mooingmilk]

Hi,

trying to setup TV out for my g/f and all is kind working, but it in black and white :(

using the svideo to composite adapter and that's plugged into the tv via the video player.

I have changed the usual NTSC PAL settings but still black and white ?

any ideas, using a Geforce 4 Ti 4200

Thanks
