I have the Motorola DCT6412 DVR and all of sudden one fine day when I started the dvr.. it said "no listings available" but it still says that it is 41% full. Please let me know if there is anything I can do. Comcast is no help whatsoever. I tried unplugging and rebooting but nothing has helped. Also, I noticed when they try to reboot it remotely or even if I try to do it.. if the cable box is on when i try to reboot after its done I have to manually turn it on instead of it happening itself. I've been trying everything but to no avail so whatever help I can get will be greatly appreciated. Thanks!
