I have been able to register my Droid 3 with my living room HD DVR, which is a QIP7232-P2. It comes up on my Droid 3 as STB1. I have been trying to register my Droid 3 with my bedroom DVR, which is a QIP7100, but to no avail. It does flash on the screen as Connecting and then lists itself as STB2, but it never completes on my Droid 3.
How can I fix this so I can control either STB?
