I've found a rather frustrating / distressing functional operation of recent HR24 Software: Automatically Deleting a RECENT Show when needing space for a New Recording. I LOST several of my highly desired (recently recorded yet unwatched) Olympics Recordings when another Olympics Event started to Record !! It used to be that DirecTV Software deleted the OLDEST Shows (not marked Keep) when the DVR became Overfull for the current Recording. However, during the Olympics, I fell behind on watching Shows (or became over-confident about HR24 recording operations). I had dozens of old 1-hr recordings at the bottom of my Content List which were "Expendable", and figured these would disappear as new Olympic Recordings were collected each day. Instead, I found that the HR24 Software was Deleting a just recently recorded equivalent-length recording (which unfortunately would be another yet-unwatched Olympics session!!). Is this a recent change ?? Is DirecTV rationalizing that "you're losing ONLY ONE recording this way" ?? Instead of losing several older shows ?? (boo...) So, I'm disappointed... And left to recover as many of the "important" sports showings as possible via the almost-exclusively-SD OnDemand offerings.
