Sorry for my ignorance but I have been reading up as much as i can about projectors and I am almost ready to jump in. Right now I have my 60" big 4:3 old tube which I am about to ditch. I have a kenwood VR3090 receiver which runs my cable, satellite, and dvd. What I do not understand and cannot figure out with the projector is, where would I hookup a cable connection since I do not see one on the back of the projectors. I want to run everything through my receiver like I currently am running unless there is a better way for better sound/video. I am currently stuck between a benq 5120 and sanyo z3. MY receiver only has svideo and video inputs. I am also using a sony progressive scan NC-655P DVD Player. Thanks for any advice.
