I think there are simply doing better error checking on the drives .. So that reliability and stability improve.
With all due respect... proper drive error checking is NOT the sort of continuous, noticeable disk activity that so many (all?) are experiencing (listen to the disk drive on your PC. its not continually thrashing...). I would not be surprised if [whatever] function is causing the xtra disk activity is also a factor in the audio & video stutters that are being widely reported. It may also be a factor in the lost disk space issues being reported. Perhaps all the checking (or whatever is happening), combined with normal recording and playback functionality is overloading some aspect of at least some of the DVRs.
The evidence from the many, probably related reports offer a compelling case that something is improperly implemented in the latest s/w release. I find it disapointing that some/many of our "experts" seem to be discounting all these reports. It feels like the old "drinking the Corporate kool aid" scenario (although I realize the Experts on this forum are not actually DirecTV employees).
