Hello, I have a HR24 as my main box, and a H21 w/ Deca box up in our bedroom. If I don't connect the internet/ethernet cord to the back of the HR24, the H21 will pick up the multi room DVR. If I plug the internet into the HR24, the H21 can no longer play multi room. This sucks b/c I can't do on Demand on the HR24, and multi room on the H21. What do I need to do to enable both of these?
