I have an HT300 Plus currently hooked up to a denon 3805 and 2900 DVD and Sky+ I wondered what, if anything, I can do to project HiDef picture (assuming that when Sky broadcasts in 2006...)? Is the projector capable of doing this with it's DVI input? I will no doubt have to change both DVD player and AV amp? Another stooopid question: What is HDMI exactly? Frightening the people you get on here eh????
