Abstract: A method for recording multiple pieces of content with a single tuner. A content delivery network can include multiple channels organized into bands with several channels per band. These bands can be transmitted on an up-link such as to a satellite. The bands can be relayed to receivers at the end user locations. The end user receivers can tune to one, two, or some other fraction of the total number of transmitted bands. When a user selects a program to view and/or record, a tuner of the receiver tunes to the band that includes the channel that includes the program. The method prompts the user regarding the other channels that form the set of channels on that band, and solicits input for recording one or more concurrent programs of the band, which can all be recorded on the single receiving tuner.
