A few weeks ago, my DVR started acting horrible. I would get "Operation Not Possible" error messages when trying to bring up my recordings. Only live TV would be available until I power cycled it. Other times I would get long pauses when playing a show and the receiver would be unresponsive for 15-20 seconds. Once after power cycling it (a daily thing) it showed my recorded list as empty yet the free space didn't go up! Another re-boot brought my shows back. Other times I would watch it record a show and then it would not be in my recorded shows list! I got a "Disk Error" message once as well. Anyway, I figured I had a disk going out since it acted horrible every day for about 10 days (it was almost entirely unusable). I just lived with it because I knew I was leaving on vacation for a week. I moved all my shows to external USB drive and powered it off during that week. When I came back I signed up for the extra warranty and intended to call in for a replacement receiver. Well, I turned it on after vacation and I have had zero problems since (about a week). Just trying to decide if I should have this one replaced still. Thoughts?
