I have finally got fed up of watching films on a 28in tv. So I am going to change garage from a junk room to a home cinema room. The thing is I know nothing about projectors, Home cinema have some but it mentions LCD DPL HPMI what are they? Most of my dvds are R1 does that have any impact on which projector to buy? Should I buy a new dvd player with progressive scan? (what is that?). In short I need projectors for dummies.
