Cool. Thanks for the answers. Here are a few questions from this thread:

1) Do I need anything for XvMC (which I gather is hardware decoding of
MPEG?) besides the right video card (NVIDIA?).

2) I was thinking of ceiling mounting the projector. It seems like it would
be good to have the computer in a corner somewhere. Are there any issues
with running such long VGA cables? I would imagine such a cable is pretty
damn expensive? The alternative would be mounting the computer from the
ceiling as well somehow so it was closer to the projector (and out of the
way).
