My recently upgraded HD-DVR froze while searching for an OTA signal and I was unable to do anything. I finally hit the red reset button under the lower right panel (as I have done in the past successfully when a bug hits). The unit went dead for longer than normal (it seemed) and when it finally returned and went through its initialization, I received a message that my interface had automatically been upgraded. I thought this was strange since that had taken place already, but it didn't immediately concern me. After I was able to return to full functionality, I discovered that my playlist was empty (~ 20 hours of both SD and HD content previously recorded was just flat gone!), my custom channel listing was no more, my to-do list of future program requests was gone and any other customizations that I had done were gone. What happened and do I have ANY recourse to get my programs back or any reason to believe that this won't happen again sometime? The DVR is ALMOST infinitely better than my old VCR, but I never had recorded programs simply disappear from tape without warning. Since keeping programs around that were previously recorded is the single major purpose of a DVR, I consider this a SERIOUS bug! Any information or suggestions about the situation or resolutions would be helpful because DirecTV Tech Support had nothing to say about it and the tech even said that she had never heard of this before!
