i have an older dual feed dish on the roof. and it works fine......

i have a DTV DVR in the living room and a plain reciever in the bedroom and one kids room. everything works fine untill i try and split one of those outputs from the splitter in the attic (4 way) w/ a 2nd splitter so i can get a signal to my reciver in the garage. onceits all hooked up, i loose channels here and there on 3 of the 4 TV's. i guess i need a single 5 way (or more) splitter since i have a need for 5 rx signlas (2 for the DVR and 1 each for the 2 bedrooms and the garage).
whats the correct fix for this? do i needa 4 output head on the dish? anyone know of any 5/6 way splitters?
anyone here work or worked for DTV?

Found these guys pretty quick: http://www.satpro.tv

Sounds like you need a wider multiswitch to distribute the signals. The Zinwell gear (like the 4803), according to their site, is DirecTv approved.

nice find.
looks like i need one of these:

right?

the one i have in the atic is a Aspen 3x4. so it appears the 3x8 will work.

Yup, you can't split after the splitter. I got a 6-way @ radio shack.

The set top boxes send a voltage signal to the antenna. I believe it's one of 2 voltages, depending on whether the STB wants to watch an odd or even channel. If you have two stb's on a coax, and they want to watch an odd and an even channel, it'll mess things up. That's the "why it's not working".
