My 722 may be losing the hard drive. For the last three weeks when I scroll out to see if any movies need to be recorded I get out about 48 hours and get a message saying :guide data is out dated, would you like to reinstall, this will take 5 minutes". For the first 5 times I said yes but the message reappeared 48 hours later every time. The next 4 times or so I did a cold reboot with the same results. All my signal strengths are good and the 722 is set to take downloads at 2am. Is there anything else I can do from my end? Thanks.
