Only Getting Monochrome Output on TV I'm connecting a late-2006 MacBook Pro with the Apple DVI to Video adapter and an S-video cable (4 pins) to a high-end but outdated TV. Unfortunately, the output via the S-video cable seems to be only black and white, whether I'm using PAL or NTSC (the TV can switch). Via the composite video output and a S-video adaptor I can get color on the TV, but I'd like to get the pure S-video output, as the quality should be better. 

I've tried changing settings and of course restarting but haven't had any luck with this.
Is there a setting I can change to get this to work, or is there some hardware restriction here?

UPDATE: I can get color by changing some settings (NTSC/52 Hertz on Mac and TV, 1027 x 768 Resolution) but the picture is pulsating.
You either have a bad adapter, cable, or TV. The S-Video standard separates the luma (dark to light) signal from the color signal. If only the luma signal is getting through, it will result in the picture being black and white. I suggest trying a different cable, and, if you have one available, a separate S-Video device. If both those work properly, your adapter has gone bad.
