I am keen to purchase one of these, but have some questions re: connectivity. I have no desire to connect a PC to it, JUST a DVD player and a Pace Free To Air Digibox. Can I use component cables for both? Or do I need S-Video for the digibox. Please advise folks! Also, can you buy a 16:9 screen which can be free-standing on a tripod/legs rather than screwed into the wall? And is a grey one better than white? Cheers!
