Just got my new install yesterday. I have 4 TVs and the following set-up: 1 HR24-500 2 H24-100 1 R22-100 Multi-Room Viewing The installer put a DECA1MR0-01 CONNECTED HOME ADAPTER ON THE R22-100. I have a wireless internet home network. The modem is near my HR24-500 and the installer hardwired it to this receiver via CAT5 cable. After he left, the only "networked receiver" I could see in the menu was the R22-100. After a session with a tech support person, she had me disconnect the CAT5 cable and then the HR24-500 became visible on the list. AShe said the the DECA unit on the R22-100 was not a "Broadband DECA" unit and that one should have been installed on my HR24-500 and scheduled an installer to come to my house to install one. I am totally confused here. I question whether there are actually 2 different types of DECA adapters as the tsr said. She said that the fact that the system works with the CAT5 disconnected was the deciding factor in her diagnosis. Can anyone out there shed some light on this/explain it to me? Also, a warning to those considering MRV: be aware that the "access" you have to a DVR does not extend to being able to view the "series manager" where a list of the series you've selected to record can be viewed so that you could see what's on that list and tweak recording options. To do this, you'll have to physically sit in front of and operate the DVR. And, of course, say goodbye to freezing live action. MRV has its function, don't get me wrong, but it should be made clearer in the selling spiel that its functionality is limited. They don't say that. They are all about telling that you "don't need a second DVR".
