DirecTV began rolling out the latest new software version for the R22 SD DVR and HR20, 21, 22, and 23 HD DVR this morning (October 23). It's version 0x0368. Release notes may be found at http://www.dbstalk.com/showthread.php?t=167093 We don't yet know if this update solves the recent issues that some folks are having with erroneous "space remaining" or loud hard drive activity, but that should become clear as this update rolls out over the next few weeks. Note that you cannot "force" an update to your DVR. Your DVR will receive the latest update when its turn comes up over the next few weeks.
