Abstract
A recording medium capable of executing menu calls based on the particular characteristics of different versions of the same movie work when these different versions are recorded on a single recording medium. An AV clip and a dynamic scenario are recorded on a BD-ROM 100 (recording medium). The dynamic scenario is a command string showing a playback control procedure relating to video data, and has attribute information attached thereto. Attribute information is information showing a control procedure for when a user requests a menu call during AV clip playback, and includes a resume_intension_flag. The resume_intension_flag shows whether playback resumption of video data after the menu call ends is intended.
