Hi, nomax,
I did the same thing you did. I had a 5x8 multiswitch feeding four UTVs. I wanted to add another, as well as a feed for an HDTV antenna. At the same time, I was changing my dish to an 18x24 elliptical with three LNBs. The choice was to add another 5x8 and cascade it using SAT splitters capable of passing the required 22kHz tone, or get an expensive 5x16 switch.
What I did was take advantage of a DirecTV promotion. Since I had TC Premier, I could add a DirecTivo without having to pay the Tivo subscription fee (normally 4.99 a month). DTV had, and still has, a promotion to buy a DirecTivo unit directly from them for $199 plus $25 shipping, and they will install the unit for you, including any needed lines AND multiswitch. IOW, whatever it takes to get it running is included in the $199. It took the installer quite a while to get this all installed, and all I paid was the $199+.
Here's the
link for the above deal.
For more information on multiswitches, etc.,
unixadm, one of the Tivo community moderator, has an excellent tutorial about this
here .
I still like my UTVs better than the DirecTivo, but for $200 installed, I couldn't pass up the deal. Since I'm not crazy about the Tivo interface, I mostly use it to record movies. I leave the everyday recording to my UTVs.
