I am setting up my old tivo series 2 up in my backyard (covered patio) where I have electric but no cable. My idea is to use MRV to fill up the tivo with watchable shows from my 2 tivo series 3 tivos in my home. My question is can I install my tivo in a vertical position (like a desktop pc-vertical)? I live in southern calif, so moisture is not a problem. I just wonder if it would be a problem if the unit is stored (& used) in a vertical position.
