We have a 2012 Expedition.  We have finally decided to connect our TVs to the Satellite system installed by Fleetwood.  We found out our TracVision will no longer be valid within a month or so.  So we purchased the DISH Playmaker Dual in order to use all TVs.  We got two Wally receivers to go with the system.  The two TVs in the LR and cab work together and work seamlessly. 

But the secondary system which is in the bedroom and supposed to also connect and view to the outside TV does not work very well.  Seems you still have to be on the same channel as the LR and cab TVs even though we have a dual connection at the satellite on top of the RV.  If the satellite channel on those changes, the bedroom TV goes out unless on the same satellite. 

And we cannot figure out how to connect the bedroom TV to the outside.  There is an input on that TV that says "bedroom" so we know there is some sort of connection but cannot figure out how to connect that -- that input is grayed out and not available.  There is a whole box under in the cabinet under the Bedroom TV that looks like it must be the system that makes that connection to the outside.  Can someone help me here. On that extra box, there is a video connection and an HDMI.  I am assuming that a splitter to that HDMI connection would allow that Wally to project to that TV?  Or is the outside TV connected through the video connection somehow? 

Gee thanks for the response. Our Playmaker is a dual which can connect two DISH wally boxes. They did work when we had one satellite -- but you are right - we could watch only watch a station that was on whatever satellite was showing in the Main TV.  THat was just not going to work for us - so we now installed a second satellite and ran the cable directly to the Wally thereby bypassing whatever splitters were in our walls which was not allowing us to connect to the outside TV.  Is the box under the cabinet in the Bedroom the one that should be connecting out outside TV?  It has a video and HDMI connectors, but neither seems to work.  I am afraid I am going to have to use the dual cable connector on the satellite and run it directly to the outside TV?
