For the most part, the DirecTV app is okay. Although, I'm running into some frustrating issues. There are many times when I start the app on either my iPhone or iPad and when attempting to watch a certain channel, I get this message, "We ran into a bit of a problem. Looks like your receiver is in use or you're already streaming on another device". I have an HR54 with 3 clients. Whenever this happens, I only have one device with the DirecTV app open. So, would anyone have any idea why the keeps happening? The funny thing is, that it doesn't happen on every channel. Yesterday, I tried to watch ch. 55 (here in NY) and that error popped up. It also happened when trying to watch ch. 634 MSGHD (which by the way, does NOT look HD). But, when I selected one of the HBO channels, it streamed. Thanks in advance for any suggestions!!
