Exemplary enhanced media content tagging systems and methods are described herein. An exemplary method includes a media content tagging system recording a live transmission of media content in response to a user request that the media content be recorded, receiving, from a media content access device, tag data representative of a user-defined tag specifying a segment of the media content, optimizing the user-defined tag, and distributing the optimized user-defined tag to another media content access device for use by the another media content access device to identify and present the segment of the media content. In certain embodiments, the optimization of the user-defined tag may be based on an analysis of aggregated user-defined tags, an analysis of the media content, or a combination thereof. Corresponding methods and systems are also disclosed.
