Hi!

I've been working on my media center box, and I've got 2 PVR-150 mce edition cards plugged in. One card works just well enough to watch while the other card doesn't work so well. The lower channels are OK, but when I get higher up they start to become fuzzy (http://img378.imageshack.us/img378/8073/fuzzyms9.gif) I know it's not the cables because I have plugged them both into my TV and the quality was great. What could be causing this problem?

Another thing to note is that, depending on what drivers I use, the screen will either look fuzzy (like above) or it will appear stretched and pulled down.

Could this be a driver issue?

My setup looks like this:
2 PVR-150s
1 Geforce FX5500
512mb ram

There's a splitter device attatched to the main cable, then the two ends from the splitter go to the PVR-150s

Have you looked at the frequency response of the splitter you're using?  Some splitters, notable the cheaper ones, have an upper limit of 500MHz. You need one with at least a 1GHz upper limit
