Offhand, a quick search for info on this leads me to believe it won't accept HDMI. It seems to accept either composite, S-video, or component video only.
This link should provide answers to any questions you might have.

These projectors are more geared to operate off of computers for business use, say powerpoint projections and such. It does reference an "M1-A" input, which is beyond my ken. I doubt it's used in home thearer, though.
You
might* get by with a "HDMI to component adapter" but I have no idea what complications might arise, or how well they operate :

* They might work with cable boxes but they say they definitly won't work for disc based media. Ya gotta love that HDCP stuff. I wonder how well it would work if you played DVD's on a computer? Would that ultimately be any better than composite or S-video?
