I am looking to put a system in. I have seen a lot of projectors. Can somebody tell me the difference between home theater projectore and the regular projector. I am looking at microtek cx6. Will this work for dvd/sat/hdtv It says it will ,but not listed as home use. I compared this to a toshiba home theater, the specs are much better on the microtek than toshiba and $2000.00 less. Please help
