Hello - At times my 611 starts making a horrible squealing sound. Then, while it is still squealing the unit freezes up. The only way to get it to stop is to reset the system. And, then I usually have to delete the program being recorded (it always seems to happen when somethings being recorded). After calling tech support, I was told I am trying to record programs that aren't are copyrighted or there is an intereference w/ the singal. Which I could believe in bad weather, but now this happens every other day. Weather is great and I'm just recording normal primetime shows off CBS, ABC, etc. Anyone know what to do? Dish won't send me a new DVR bcuz they are claiming there isn't an issue. And, I am sick of spending money for this when I can't trust it will actually let me see the shows being recorded. Thanks.
