Dolby Digital Audio Track is shown as "dolby surround"

When watching content with a selected dolby digital audio track (2.1, 6.1, etc..). You can select the output-mode under the channels sub-menu. This menu shows an entry called "dolby surround". But "dolby surround" is a (rather old) "encoding" system for analog stereo transport. The entry in the channels menu should be changed to the correct "dolby digital". At best with an additional value for the channels (2.1/6.1 etc...).
