I have an extra Tivo that I want to give to my brother. I do not have the cables for it, as it was a replacement from Tivo. The original cords I had given to someone else. My question is this....I know i need to buy him a new remote from Tivo...but can I buy the other cords (power, ir blasters and rf coaxal cable) from someplace locally like Radio Shack? (where they will be cheaper) Or do I need to get everything from Tivo?
