How do I get a 2nd device to show up in the Program Guide?

In my DVR I have an HDHomeRun PRIME and a HDHomeRun DUAL set up (Windows 7 PMS Version 1.10.1.4602). Right now only the PRIME is showing up in the program guide. I would like to be able to use both. How can I get the channels on the DUAL to show up as a choice in the program guide?

Plex only supports one Program Guide in a DVR. If your channels available on the Dual are also available on the Prime you might be able to match them up when adding the Dual to your DVR. I have a Prime setup in my OTA DVR of HDHR Connect(s) but only receive local channels rebroadcast by Cable company using the Prime, luckily for me the channels match up perfectly to the OTA channel, so 10.1 on the Prime matches 10.1 received OTA on the Connects.
