My two different generation Sony boxes are set up the way Isellstuff suggests, with a splitter at the phone jack, and everything is fine. Two different GUIs and one has Tivo while the other doesn't, but the exact same programming.

I wanted to avoid the multiplexer thing so I just used both LNBs at the satellite dish for hookup. I'm using the 6 year old dual LNB round dish because I just couldn't the new oval dish with the 4 LNBs to see all the satellites. Someone I know uses the multiplexers for multi-room feeds and it works great.
No no no no no!

Not a multiplexer--that layers one signal on top of the other. You need a *multiswitch* because you need to be able to access both the odd and even channels, which requires signalling to go both ways--you need a *SWITCH*. This is why you get only half the channels (I suspect either odd or even, depending upon how the other boxes were set). Look here for a quick tutorial:
