I think you are right. I saw a cable that does DVI to Component, but
after reading your post I looked at it closer. It specifically says not
meant for PC unless the video card explicitly states compatibility.

That sucks, really was hoping not to have to buy more components. That
will put a serious dent in the WAF.

The projector is an Infocus X1. It has these inputs:
VGA
SVideo
Component

According to the manual it achieves HD using the component to SVideo
adapter included. As you said, not really SVideo at that point, but
that's how I get it to the projector. 

The VGA connection sounds like an option, but besides needing a prettly
long VGA cable, here's why I don't want to do it that way. My receiver
is the center of my home theater setup. All the A/V gets piped through
it. As for video it has SVideo, Composite, and Component output. That
way all my wife had to do is switch the receiver to the correct "device"
setting and everything is taken care of, rather than having to switch
multiple devices. IE, switch the projector to SVideo for DVD, and switch
to VGA for Myth. 

So it still sounds like the ideal situation for me is to somehow get
component output of the PC. There are certainly cost issues involved,
meaning I don't have a lot to spend on this without seriously lowering
WAF to the point of non-acceptance!

Also sounds like I might have to do this in stages. I could just get a
cheaper NVidia card doing component or SVideo out and move to HD when I
can come up with a PC that can handle it, but I still need to figure out
how to get PC to component. Not thrilled about needing to spend $100-
$150 on a converter for that, like VGA to Component converters.

Any other info/opinions/suggestions?

Thanks,
James
