I ordered an HR20 to replace my R10 in my bedroom mainly for the ability to record in hd. After reading about some of the bugs and the fact that people are having missed or partial recordings, I'm really starting to think I might have made the wrong decision. How reliable is the HR20 and what can I expect as far as missed or partial recordings go? I'd really like to give the HR20 a shot, but not if it means missing recordings.
