Thanks for the reply skeg. I saw that thread earlier today while I was doing a little research on my Cenexant chip. It's true that the CX2388x cards only capture 688 horizontal pixels. However, this is due to clipping on the sides as I found out using a program called Dscaler. With Dscaler, there are a ton of advanced settings you can tweak for your captue card, and among them is the clipping setting. When I uncheck this, the whole 720 pixel resolution can be seen. The major drawback to this is that you can't capture (stabily) with this program.

Another thread I found over at doom9 has a hack that will allow access to those advanced settings and still let me capture with VirtualVCR. Some if what they're talking about is way over my head, but I think I understand how to do it. And as soon as I finish, um, acquiring a visual basic compiler, I should be able to give it a try. I'm excited to see what other things I'll be able to tweak with this.
