. Determines when a Dolby Digital decoding
product also contains a Dolby Pro Logic decoder, whether the two-
channel encoded bistream contains a Dolby Surround (Lt/Rt) program
that requires Pro Logic decoding. Decoders can use this flag to
automatically switch on Pro-logic decoding as required.

, Dolby Surround; the bitstream contains information
that was Dolby Surround encoded. After Dolby Digital decoding, the
bitstream is pro logic decoded.
#Pref dwnmx Preferred Down mix. This parameter allows the user to select either
Lt/Rt or the Lo/Ro downmix in a consumer decoder that has stereo
outputs. Consumer receivers are able to override this selection, but
this parameter provides the opportunity for a 5.1 channel soundtrack
to play in
Lo/Ro
mode without user intervention. This is especially
useful on music material.
