Query: Poor/confusing UI client application, remote not reliable.

This is one of the worst electronics products I have ever bought. The remote is not reliable, it doesn't store its state correctly (I switch off my PVR in the evening, and in the morning it only switches on TV, I have to switch on PVR and Audio manually). The remote also does NOT support two tuner DVR/PVR like DishDVR 522.The software client is web application which has very poorly designed UI with even worse Help system. The application is also unreliable, sometimes it fails to update changes (download) on your remote.It is still useble product, but just barely. Prepare to do a lot of experimenting and bring a lot of patience.
