I got the sling adapter the day it came out and hooked it up to my 722. It worked like a charm out of the box EXCEPT that I can not control it via the iPhone app. When I go in from the web, I can do everything, but from the iPhone I can not select a DVR item to play back or control the unit. All I get is live TV and can't pause it or anything. Anyone else have this issue? Like I said, it all works perfectly when I access from the website on a computer.
