Both my DirecTV HD DVR's have a "Queue" function in the Manage Recordings Menu section. When I click on Queue it shows: Programs & Preferences, when I then click on Program it shows: Items/None, when I click on Preferences it shows Keep At Most: 10 Programs. Both DVR's are actively recording a large number of series and individual shows normally. I can't see what purpose the Queue function serves. Can anyone here explain what the purpose of the "Queue" function is? Thank you.
