How do you have your gear connected though? Are you also using the DirecTv receivers?
If the gear you want to connect is located near a DVR/receiver that uses an external DECA you can connect like this > http://www.dbstalk.c...506#post3141506
If the DVR at that location has an internal DECA, e.g., HR24, you can split the coaxial line that will feed that DVR with a green label splitter....one leg will go to the DVR and the other will go to a CCK as explained here:
If you have a dedicated coaxial cable at the location where your other gear is connected, you won't need the splitter.
