Media Player Accessibility Features

QuickTime:

The ability to turn captions on or off is only found in QuickTime Pro ($29.99, from Apple). The free, downloadable version of QuickTime does not have this feature, but users of the free version can upgrade at any time by purchasing a license number from Apple. Whether captions play in a QuickTime movie by default depends on the author of the QuickTime movie. If the author saves the QuickTime movie with the caption track on, it will play by default in all QuickTime players. If the author disables the caption track before saving the movie, the caption track will not play by default, and will thus be accessible only to users of QuickTime Pro.

The QuickTime 'Enable Tracks' dialog displays all tracks in a QuickTime movie, but unless the developer provides names that are easily understood it is difficult to know which track to enable.
