if you decide to get long component cables it will indeed cost you a fortune to get such long cables, so i would recommend using some coax cable with rca plugs on the end. i have worked for places where that is what they use (albeit made by someone else) and it works fine.

you have a dlp tv though, and it would benefit more from the dvi than it would from component. plus you will see more loss on long analog runs than you will on long digital runs.

seems kind of strange that dvi is only rated for 5 meters, they are obviously making a tradeoff somewhere that sacrifices the ability for the signal to travel long distances.
