I apologize if this has been answered -- I did a search and while there is SOME info out here, I can't seem to find a final definitive answer. I have a 2 LNB dish and run 1 of 2 output wires into a Diplexor at my OTA Antennae. So currently I only have 2 wires that run into my house - neatly BEHIND THE WALL. The feed from the diplexor of course then is "split" into my HR10-250 so that I can pick up OTA HD as well as the 2 Satellite inputs. When/if I do the upgrade to the new HR20, will I be able to use the existing lines into the house (Mpeg4)? (seems like if there is an addition Sateliite, I'll need another cable.) Or will I be required to run yet an additonal Cable(s) into the house? This is my issue - it will be next to impossible to run another line in along side the other 2 ... and may be the deal breaker for us to stay with D*. Does anyone know of a link of a picture for how this new setup is configured? Thanks in advance.
