I've been scouring the internet and I can't find what I'm looking for. The past month or two our 722k is losing timer info. I noticed when it didn't record a new episode of Ax Men. I went into the timer and there was nothing there. This has since happened to probably a dozen or more timers. I can resetup the timer and it will start recording again. I can't find a reason why this is happening and can't find anyone else that is having this problem. I've done a reset and gotten new guide data manually many times. Is my receiver corrupted or something? thanks!
