In one embodiment, a method receives a request from a user for one or more extensions to a first program. The first program is associated with a first bundle that indicates the first program starts at a first time and ends at a second time. A second program that starts before the first time or starts after the second time is selected. The second program is associated with a second bundle that indicates the second program ends at the first time or starts at the second time. The method generates an extension bundle that includes information for the one or more extensions and uses the extension bundle to record an extended program for the user that includes the first program and at least a portion of the one or more extensions from the second program.
