laptop to X1 and a cabling question

3 hopefully simple questions.


1. If running through VGA out port of computer (watching DVD), is that effectively a 'progressive' DVD player?


2. When trying to watch same DVD through S-Video out on computer (just as a test), everything (all icons, text, etc...) shows up fine except the actual video, which shows up as a blank black screen...tried windows media 9 and a couple of other players, all with the same result....what's going on here?


3. When running cabling from projector to controls, (component and s-video), i am under the assumption I should separate the controls wires from the power to the projector and run them through separate conduits/routes...is this necessary?


thanks in advance....
