Sorry for the no-no Alan! I figured I'd move the thread here because I actually use an Pro-HD.
I use slingbox.com to watch at home, and I also have the mobile app for my iphone. When you say they've removed custom remote functionality, what do folks in my situation do? Frankly at home on my primary mac is the least of my problems, because my mac is in a spot that gives me line of sight to my IR repeater, so I could use the actual remote for the HR-21. But I've lost all ability to control the box with my phone, and we also have a laptop.
I really wish I hadn't had to reset because I've had zero problems since you last helped me a year ago, but my box wasn't being recognized by slingbox.com.
