Alright, here's what I think I've figured out so far. If I get a video
card with DVI output, preferably nvidia because of the good linux
support, I can convert DVI to component. From there I can convert
component to what my Infocus projector wants using the included
adapter. 

I have a machine that I was hoping to use for this system:
Athlon 1400+
768 Meg RAM
plenty of disk

Two problems with this machine:
No PCI Express or AGP slot, so are there any NVidia cards I could use?
Is it enough to handle HD with an HD3000?

Other question still remains, if I get this setup working, will I be
able to view regular recordings, MPEG2, through this TV Out? I'm
assuming yes right now.

Thanks,
James
