I have always noticed , that when your hard drive gets filled or close to it , your reciever will get sluggish , I try to keep my DVR'S cleaned at a minimummnumber of shows and they seem to run smoother....
How do you force the download during the window of opp , I can't remember , I know its while your rebooting the reciever , and have to type hit some numbers on the remote , could someone give me the short version......Thx!
