Is anyone else experiencing this? A couple of times recently I have turned on the tv to discover that I had no free tuners to watch anything. When it takes me to the screen that shows what each tuner is doing, I see each tv show listed twice. So just now it showed it was recording Shark Tank twice, Grimm twice, etc etc. The only way to get back to where I could watch something other than what was being recorded was to power cycle the receiver.
