My HR22 has been acting weird today. It's been randomly losing the connection with the satellite even though the weather is totally clear, then while I was watching Iron-man it completely just stopped working. I could pull up the guide and change channels but every channel was just black, no audio. Tried to go into the menu and check the satellite signals but then it just froze. I hit the reset button and after getting through all the startup stuff it seems to be working but it did just drop the satellite signal briefly again and it has me worried. Any advice?
