7. The media player of claim 6, wherein the media analysis component determines whether a branch is invalid by evaluating a menu item associated with the branch.

8. The media player of claim 7, wherein the media analysis component determines that the branch is invalid if the menu item associated with the branch would not be visible on a display.

9. The media player of claim 7, wherein the media analysis component determines that the branch is invalid if the menu item associated with the branch is smaller than a menu item size threshold.

10. The media player of claim 7, wherein the media analysis component determines that the branch is invalid if the menu item associated with the branch would be presented on a display for fewer frames than a menu item frame threshold.

11. The media player of claim 6, wherein the media analysis component determines whether the branch links to an invalid portion of the recording medium by walking the portion, and wherein, if the portion is determined to be invalid, the portion of the recording medium to which the branch is linked is not identified as a valid portion of the recording medium.

12. The media player of claim 11, wherein the media analysis component determines that the branch links to an invalid portion of the recording medium by determining that the portion comprises an infinite still frame.

13. The media player of claim 11, wherein the media analysis component determines that the branch links to an invalid portion of the recording medium by determining that the portion comprises cyclic data.

14. The media player of claim 11, wherein the media analysis component determines that the branch links to an invalid portion of the recording medium if a number of read errors encountered within the portion exceeds a read error threshold.

15. The media player of claim 1, wherein the media analysis component generates a graph of valid portions of the recording medium, and wherein the graph of valid portions of the recording medium comprises one or more segments of the recording medium interconnected by one or more branches on the recording medium.

16. The media player of claim 15, wherein the archival component stores the media content on the portions of the recording medium within the graph.

17. The media player of claim 1, wherein reading, identifying, storing, and playing back of the media content is to commence in response to a single command for playing back and recording the media content from the recording medium.

18. The media player of claim 17, further comprising a single user interface component to receive the single command for playing back and recording the media content from the recording medium.

19. The media player of claim 1, wherein reading, identifying, and storing the media content is to commence in response to the recording medium being inserted into the media reader without an explicit user command to store the media content.

20. The media player of claim 1, wherein the media analysis component identifies as invalid all of the portions of the recordable media not identified as valid.

21. A method comprising:

identifying portions of a recording medium as being valid or invalid;

storing the media content of the valid portions of the recording medium in a storage medium; and

playing back the media content of the valid portions of the recording medium from the storage medium concurrently with identifying the portions of the recording medium and storing the media content.

22. The method of claim 21, wherein identifying the one or more portions of the recording medium as being valid or invalid comprises walking a structure of the recording medium.

23. The method of claim 22, wherein walking the structure of the recording medium comprises reading and discarding data read from the recording medium.

24. The method of claim 22, wherein identifying the one or more portions of the recording medium as being valid or invalid comprises emulating a media player.

25. The method of claim 24, wherein the recording medium is a DVD disc, and wherein emulating a media player comprises reading data from the DVD disc and executing DVD virtual machine instructions as a DVD player.

26. The method of claim 22, wherein identifying the one or more portions of the recording medium as being valid or invalid comprises evaluating a branch linking to a portion of the recording medium to determine whether the branch is invalid, and wherein, if the branch is determined to be invalid, the portion of the recording medium to which the branch is linked is not identified as a valid portion of the recording medium.

27. The method of claim 26, wherein determining whether the branch is invalid comprises evaluating a menu item associated with the branch.

28. The method of claim 27, wherein the branch is determined to be invalid if the menu item associated with the branch would not be visible on a display.
