So are you saying that DVI/HDMI over 15 ft. should NOT be considered? Here is my dilemma. I have to run about a 40' DVI to HDMI cable up, over, and down. Should I reconsider this by using component cables? This is going from a HTPC to a Toshiba DLP, where the rack is not on the same wall as the DLP. I get a great picture running homemade 40' component cables, but now concerned about connecting the HTPC.
