How to conect a compter to a LCD or Plasma that is 25 feet away

OK, here is the situation – new computer store, have a JVC camera that will feed USB to machine, Video feed monitor and I want a hi-def TV hanging on a wall 25 feet away.

I want 29 FTS on the TV, I know I can run dual “monitors” but TV is s-video. I want to be able to feed what’s on the machine to the TV with good resolution, I welcome options on the best way to do this, both computer monitor and TV must display same without compromising FPS????
