I have had similar issues as many others have with my HR34 unit; screen freeze with audio continuing. Got Direct to do a swap with another HR34 and unfortunately had the same problems. After a software update that specific problem went away but it now becomes frozen and unresponsive requiring a reset. The most recent time after it froze I heard a strange noise coming from the box. It’s a series of electronic beeps and clicking. I know clicking can be a hard drive but as for the sounds I’m stumped. Any ideas on what it could be? I have never gotten any tempature warnings or other error messages on screen.
