What you need is a MultiSwitch, for your system. Ebay is your friend.
I just bought one for my new DirecTivo so that I can have it and my 2
old receivers all running off the one Dual LNB. cost me about $25US

Bruce:

How will that work I know I can put a multi switch between the LMBs and the
boat but how can I take two separate inputs into the TIVO unit, I thought I
could use another multiswitch to split the signal into two inputs
(satellites 1 and 2 on the input side of the TIVO) but the installation
technician said no. Fred



Multiswitch has 3 inputs.
1. RHCP
2. LHCP
3. Terrestrial Tv

Multiswitch has X number of outputs. Where X is 2,4,6,8, or 16.

Each output is switched between Input Port 1 or Input Port 2,
depending on the selected channel of the DTv receiver.
If it needs RHCP then the receiver outputs +12Vdc on the antenna lead.
If it needs LHCP then the receiver outputs +18Vdc on the antenna lead.

So you connect your Tivo's Two (2) Antenna Ports to two (2)
of the MultiSwitch output ports, and connect your old
DTv Receiver up to a third output Port and have three channels
of live Tv coming into you boat. Two for the Tivo and one to the
standalone DTv Receiver.


Bruce in alaska who has six (6) DTv receivers scattered around
the homestead, all off one 1.5M dish with
a dual LNB...........
