There are different types of Dolby Surround.

Dolby Surround or Dolby Pro-Logic are 2-channel stereo modes which simulate a surround speaker (rear) and a center channel (in the case of Pro-Logic only). One of my dad's TVs had this codec on-board. Dolby Pro-Logic isn't bad which is why the codec has evolved into its current incarnation - Pro-Logic IIz for use with legacy stereo recordings.

Dolby Digital, and Dolby TrueHD are discrete 5-channel surround modes.
