S-Video blur

Well I got rid of that static in my TV but now it's a little blurry. I am running my laptop through to my TV via an S-Video cable that goes to this box which you plugin a cable into, then it goes to the TV. I've tried at many resolutions and still no luck. I've tried at:

600 x 400
800 x 600
1024 x 768

And it doesn't come out right at all. Still a little blurry. Does anyone know how to remove this blur? It's hard to read text but when it comes to playing games itself, it's mint quality, except for the cars in Underground 2 looks like they are doubled a little. Looking at my TV you would think you were drunk. In a way it's like watching a 3D movie without the red/blue glasses. That blue and red blur along the outside, except it's the color of the object.

Thanks

I take it you don't have this blurriness when you run the TV with regular video input?

This sounds like a divergence problem which generally requires an adjustment of the video amps feeding each of the guns, but in this case, I'm thinking either the S-video output of your laptop is cheesed or (more likely, IMO) your S-video to video (or RF) converter is causing the problem.
