HELP - I've seen a set-up for coaches who use a tivo in conjunction with a camcorder and tv to record athletes performing on delay so that they can view their skills. So I bought a Tivo and can't get it setup. Do I have to subscribe to Tivo to make mine work or is their a way to utilize the anteana input? Also I've heard that by buying a Series 2 it won't work - only with series 1 the very first models will this gym setup work. Any ideas?
