We've been having issues with 2 of our DVRs since the 9/30/15 software update. Our HR23-700 has been freezing several times a day requiring a red button reset. Our HR24-500 also freezes but more infrequently like every other day and freezes on American Express commercials and must be reset to restart. Called DirecTV and they said they were aware of an issue with freezes on commercials. Logged my input and said they were working on a fix. Anyone else experiencing these issues since the sw updates?
