We've had this HR54/500 (6 TB) for about a year and a half with no problems. 8 SEP, 3:29a MST: Software version 0xd80 comes on line. 8 SEP: I go to bed with 1% Free. 9 SEP: I wake up to find 10% Free; oldest recordings seem to be intact. I call D* to ask tech. support what is going on, and the guy ultimately says that the new software is compressing our recordings so that customers can have more space. 9 SEP, late evening: After being out of the house for several hours, I find 11% Free despite that multiple recordings have occurred and I haven't deleted anything. While wasting almost 1.5 h on the phone with D* (including System Test, red-button reset, and an escalation), I look at the History and Playlist more thoroughly, and I find that many seemingly random recordings are both listed as Deleted and missing from the Playlist. I delete a couple movies or so, thinking this is some new mandated-10% BS that I can stem through manual intervention, which gets it to 12% (over 700 GB = well over 100 h of HD). D* is unable to transfer me to "level 3" support, but I am told to expect a call from them in the morning. 10 SEP: 13% Free then 12%; no phone call as of 12:37p While I thank you all for this and prior help, direct and indirect, I request that anyone posting to blame this on hardware to please have a solid, detailed explanation.
