I have a the single room Tivo and am looking at either Dish Netork, DirectTV or Charter cable. Dish Network has the better prices, but I'm getting conflicting answers on whether or not Tivo is compatable with Dish Network. Tivo customer service says yes (only with single room Tivo box). Two calls to Dish Network have said no not at all and yes but you lose the functionality of Tivo. So does anyone here have an answer?
