I think Monoprice.com has some adapters or cables of some sort to make things like this work.
Getting HD cable signal to Infocus X-1 projector
Trying to get a proper HD cable signal to my Infocus X-1 projector. Problem is the box has component and DVI-D connections. The projector only has VGA, S-Video. Right now, I'm just running S-Video out of the projector, which is not terrible on HD channels. Just thought I may be missing an even better picture available.
