I've had my HR-20 for over a year. After some initial problems with it, it has been rock solid for me. I just got an additional HR-21 700 a week ago and it missed 2 recordings yesterday.
I scheduled it to record the minor league futures game on ESPN2 and a movie on ABC Family in the evening. When I click play on both shows they come up blank and immediately ask me if I want to delete them. I was able to record a third show yesterday but that one was manually recorded. The two shows that failed to record were both programed recordings. Where should I start to figure out why this happened and prevent it from happening again. I'm running 0x235.
