I have a couple quick questions regarding this projector. I had all of 45 minutes to play with it before having to go to work. 1. Why is digital cable black and white when I hook it up through S-Video? 2. What is the best method for turning it off. Do I want to flip the switch on the side or just use the power off on the remote? (I am looking to conserve lamp life here) 3. Why must the projector sit two feet from the ground in order to project onto the wall? I had really wanted to put it on the top shelf of a bookshelf but the image is halfway on the wall and halfway on the ceiling. Please talk SLOW, as I am a total newbie when it comes to projectors.
