Well, I went ahead and pulled the trigger. I am a current E* customer that is switching to D*, mainly because of the HR10-250 HD TIVO. I really want the ability to record HD (both satellite and OTA). I also want dual satellite and OTA tuners, and HD TIVO is the only unit that will give me that. I ordered the equipment from Value Electronics (HD TIVO, SD TIVO and a third room with a regular receiver.

Has anyone had any experience with the installer they (Value Electronics) use in NW Atlanta? I have read some horror stories (not about their installer, just in general) and I would like to know what to expect.

Also, I because of the 3-room installed I had to order a 5 X 8 multiswitch from them. I am not sure I fully understand how a multi-switch works. I know I need five lines out 2= HD TIVO, 2= SD TIVO, and 1 regular receiver. I also know that only four lines can come out of the LNB. My question is how many lines are needed for the mulit-switch to output 5 signals. By this I mean, how many lines in are required minimally, and if different, how many lines would be optimal for best performance, and why?

The reason I ask is that I have 3 lines currently running from my E* dish in the back yard to the house. These are good runs, buried underground, and I would like to not have to dig them up and add another line, if it is not necessary.

You need 4 connections between the satellite dish and the multiswitch. If necessary, you could utilize 3 coax cables for this by using a stacker on the two signals from the 101° LNB to combine them into one cable and destack them before they enter the multiswitch. It would cost you just under $300 in parts to do this. Look at the description of stacking the signals from the 18" dish at http://www.9thtee.com/dssstuff.htm ; this is what you'd do, even though you're using the Phase III 3-LNB dish.

A DirecTV multiswitch makes available any of a given number of LNB signals to each receiver. Each output of the multiswitch receives a voltage and/or 22kHz tone from the tuner connected to it to identify which of the signals the tuner is asking for (actually now with the satellite at 72.5° and 95°, there's a few additional potential signals a receiver could ask for, but it works on the same principle).

Thanks for the response. But I think I've decided to go ahead and have the installer run four new lines from the Direct dish and a new line from the roof-top antenna without any breaks into the multi-switch. The run the necessary five lines out. In my current, configuration I have a couple of joins, and at least on diplexor. Hopefully, in combination with the more sensitive tuner on the HD TIVO, my OTA signal will improve on my marginal channels.
