I need help with my HTPC and its component cable connection. I'm missing the blue channel.

This has had me stumped for a long time. I had a 2600xt in my HTPC that plugs into my TV. Its an older set, so i'm forced to use the s-video to component adapter to get a picture on the screen. It all works but...
I have no blue color. When i have the default windows 7 background up, (which is blue) the picture looks like a greyish blue. As in the blue is completely absent from the picture. When i unplug the cable from the blue plug on the adapter, the picture stays the same.
Things i have ruled out:
The adapter cable is fine, i tried a diffrent one, same issue.
The cable from the adapter to the tv is fine. I switched the plugs around from the diffrent color channels and they all work fine
The TV is fine. The blue is there when i switch it over to the satellite or DVD
I may have found the issue, but i'm not sure if its correct. The S-video out on the 2600xt is only a 7 pin s-video. The adapter i have has 9 prongs. Where the 2 extra prongs would go is a cut out for a plastic insert from the male cable. I'm guessing those 2 pins control the blue channel.
So im looking at a few options, Find a video card that has a 9 pin s-video out so i can use the adapters i have. Or, i can try one of those iffy DVI to component adapters. All of them have horrible reviews and never seem to work for anyone.
If you can find a graphics card that has a 9 pin s-video out, please send me a link. Otherwise, is there any adapter i could use that would work?
