Sorting on the DVR. Can it be permanent?

[bszen27]

Hello. Every time I try to sort my DVR (Arris VMS1100) shows, everything works fine at that moment, but it doesn't STAY sorted. All I want is for my older shows to appear first permanently, but the DVR just won't allow it. If I leave the current screen, it goes right back to the default sorting method. I have to think this is an oversight in terms of the coding or maybe I am just missing something. Any assistance would be appreciated.
