Be warned that if you have a set top box model VMS1100, the box can run a system upgrade at any point which can remove half the storage capacity and then delete all programs over the limit. This happened to me this week, and the box deleted 8 months of shows I had programmed. I was on the phone with Verizon for several hours, and they said this is a known issue, and there is no way they can recover the shows. They actually completely deactivated my boxes in the process of trying to fix it, so now nothing works. They offered to send a new box, but that will remove all my recordings. I pay for DVR to have my shows when I want them - not so that they can randomly delete my programs with a known system error.
