Abstract: A media recording system may be provided. The recording system may include features for reducing recording cut-off of a particular media event due to changes in the start time and end time of what is scheduled to be recorded. The recording system may provide a user with an opportunity to select a program by for example, selecting a listing, to have that program automatically recorded at a scheduled time for presentation to viewers. Changes in the schedule of programs may be compensated manually or automatically when the recording system receives information about actual or predicted time changes. In a manual mode, a user may adjust start or end times based on time change information that is displayed. For an automatic mode, the recording system may automatically compensate for predicted or actual time changes that are known by automatically adjusting the start and end times of recording.
