Here is a good tip for those with Multi Room DVR.
My wife and I found ourselves in a situation where we were watching the season premire of Dexter and my newborn son woke up. We were watching downstairs on our non-DVR HD box, and had no way to pause the show. My wife had a great idea to use remote DVR from my phone to start recording the show, then to resume playback from the recorded content. It worked like a charm.
Now, I can't figure out why I just couldn't press the pause button or record button and circumvent the entire remote DVR work around. It definitely is not a hardware issue, the workaround demonstrates that it should work. I guess the issue is getting the STBs to play nice and communicate commands to the DVR. This would be a great addition to Multi-Room DVR.
