The above links are snapsots of what I get from s-video and composite signals.
Does anyone know why I get this bad image from the s-video?
I tried to connect my VHS to my TV with the s-video cable and it worked fine. So it's not the cable.

I have the latest drivers from nvidia, directx9.0b, 1024x768 resolution, 16bit color and I've tried another s-video cable.

I took out all the other PCI cards from my computer and left pctvpro only.
I also disconnected CD/DVD drivers and started the computer with a clean installation of winXP. Again distortions!!!
I also cut the power off the fans (cpu, case). Again distortions!!!
Furthermore, I got signal from the TV-Out of my GeForce4 Ti 4200 using the s-video cable and again I got the distortions.
Then I tried to change the "Spread Spectrum" option in the BIOS, cause I thought that these are EMI (Electromagnetic Interference), but nothing happend!

Maybe is the PSU (power supply). I can't test it cause I don't have one.
I will search for shielded s-video cables, although I haven't heard that they exist.

Thanks.
