I have a dish 500 with a dual LNB with DP 34 switch which is connected to my 721 which uses 2 of the outputs from the DP 34 and a third line from the DP 34 is going to my 501 in another room. The question I have is can I run a fourth line from the DP 34 to a SA Tivo series 2 and it work without paying the monthly fee to Tivo. I have heard that Tivo has a very basic interface that it can use if you decide not to pay the fee. I am not wanting to cheat Tivo in any way I'm just trying to be frugal. Of course all of the questions about the Tivo are moot if it will not work from a fourth output on my DP 34. Thanks for any help. I hope this is in the right forum I searched through the forums and this one looked like the closest one to my post.
