I have been getting this message for the past couple of weeks and it's even starting to interupt timers. I turn my tv on and it says that there is a problem with some switch or something and to check it but when I check it all is well. Everything is green and ok and when I do a test that turns out fine too. Can anyone tell me whatis going on? Oh and two nights in a row a timer acted like it was recording but wasn't actually recording. No red light just a "record" symbol on the screen. Even when I tried to turn the channel it gave me that "you must switch to live mode" msg but it didn't record. I had my 522 for 2 1/2 months is it dying already?
