              Prints the transport settings being used by QuickTime for streaming media.

     read MimeSettings
              Prints the MIME types currently being handled by the QuickTime plugin.

     read MediaKeys <category>
              Prints the media keys being used by QuickTime to playback encrypted movies.  The optional
              <category> parameter can be used to list only the media keys associated with the specified
              category.

     reset DownloadCache
              Empties the cache being used by QuickTime to store downloaded content.

     reset TransportSettings
              Resets QuickTime to automatically determine the best protocol and port for streaming media.

     reset MimeSettings
              Resets QuickTime plug-in to handle the default MIME types.

     write LegacyCodecsEnabled <value>
              A <value> of "yes" will enable the legacy codecs for use in the export settings and a <value>
              of "no" will disable them.

     write MediaKeys <category> <key>
              Adds the media key specified by <category> and <key> values to the list of media keys used to
              playback encrypted movies.

     write TransportSettings [protocol [port]]
              Sets QuickTime streaming to use the transport settings as specified by <protocol> and <port>.
              Following are the recommended values for <protocol> and <port>:
                    - To use HTTP, specify <protocol> = HTTP and <port> = 80
                    - To use UDP, specify <protocol> = UDP and either <port> = 554 or <port> = 7070

     delete MediaKeys <category> <key>
              Deletes the media key specified by <category> and <key> if it exists.
