I have an HR20 HD DVR. I know I used to be able to schedule recording from my phone, but I haven't been able to lately. I tried to set up a football game while traveling yesterday (in Mexico on wifi if that matters) and when I got home, it wasn't recorded (the team I was rooting for lost so maybe it's a good thing). Directv's site says the request goes through the satellite, so is the issue I was in Mexico? I know it says it doesn't have to be connected to the internet for remote scheduling, but does this have anything to do with it - in the iPhone app, under my receivers, it shows my receiver, but it's greyed out and in the IP address section, it says, "Control Status: Blocking Access." The IP address is correct. Do I need to open a port in my router? I tried searching online, but I can't find anything about that. I just tried redoing the connection guide and it's using a different IP address, but it's still saying blocking access. Any ideas?
