I had this exact issue on the very first recording I made the first day that I received my HR20 back in October. It has recurred quite frequently. I wonder what D* means when they say they improved stability on a a given release. It's such a vague statement. Frankly I have not noticed any improvement in reliability in the 3+ months I have owned it. The running joke in our household is that the HR20 is actually a Cylon.
