Install for townhome with total home DVR

The beauty of Single Wire Multiswitch (SWM) technology is that only one cable is required, even for dual tuner DVRs.  And it supports the DECA coax networking needed for Whole Home DVR sharing.  So having only one coax cable from your wall to each room is not a problem.  

With one HDDVR and three HD Receivers, you'll get a SWM dish that has one coax cable from the dish to your central wall location. There the installer will use a SWM splitter to feed one coax to each room with a DirecTV DVR or Receiver.  A power inserter will be installed near one of the Receivers to provide power for the dish LNB.  And DECA adapters will be added to each Receiver or DVR that doesn't already have them built in.  And be sure to specify the Cinema Connection Kit on your order so the installer can "bridge" the DECA coax network to your home network for internet access to all of the DVR/Receivers.  It's no extra cost. 

Call DirecTV and they can set you up.

Ok, thanks for the explanation.  Another question, I currently have cable internet, which is split at my main TV, one for my cable modem and one for my HD DVR.  I know I will no longer be able to do this.  I was thinking of switching to DSL, since it uses the phone line.  However I know how fast my cable internet is, and it is much faster than DSL, so I could use my coaxial in my garage to accommodate cable internet, thus allowing me to use all of my other coaxial lines for my satellite TV.  How exactly do the receivers attach to the internet, wired or wireless.  And also what is the internet connection used for; total home DVR, on demand, or both.  Thanks again for the quick response.

yes you can def move your modem to the garage to free the run at the main TV.  the concern is if you would get acceptable wireless reception to your devices.

DTV will connect a BB DECA adapter to your HDCP enabled router, this adapter will connect your all of your DTV capable boxes to the internet via the same coax that feeds the satellite signal.  DTV uses DECA for networking which is a cousin of MoCA, but different frequencies.  google MoCA to learn more about networking with coax

Be sure to decide your internet provider before DirecTV comes to install their stuff.  As part of the Whole Home DVR installation they'll provide the Cinema Connection Kit.  They'll run a satellite cable to a location near your internet gateway/router and install the CCK there with one connection to the satellite coax (DECA side) and one connection to your router (ethernet side).  There is also a wireless CCK, but the ethernet connection is the most reliable.  

Internet is used for CinemaPlus (OnDemand) show and movie downloads, TV Apps, reporting PPV purchases and more.  It's NOT used for WHDVR sharing between the DVRs and Receivers because that's done within the DECA coax network.  

I'm set to have Direct TV installed next week and was going to have my contractor run the coax cable from the roof to the basement (I don't like the unsightly way they run the cable along the outside of the house). How many coax cables do I need running from the roof to the basement? From the basement the coax cables run to all the rooms of the house (1 cable per room). Right now I have 3 TVs. Will this setup work?

You should only need one RG6 solid copper core coax cable from the dish's location to your basement wiring panel.  

one RG6 is good for up to 8 tuners.  DVR=2, receivers=1.. if you ever plan to get more than 8 tuners, you will then need four cables from the roof to the basement.

Have the electrician run the cable past your service entrance and leave about 4 feet of slack so the Directv installer can put in the ground block and rain loops.
