1.28 The disc says Dolby Digital. Why do I get 2-channel surround audio?
Some discs (many from Columbia TriStar) have 2-channel Dolby Surround audio
(or plain stereo) on track one and 5.1-channel audio on track two. Since
some studios create separate sound mixes optimized for Dolby Surround or
stereo, and they feel the default track should match the majority of sound
systems in use. Unless you specifically select the 5.1-channel track (with
the audio button on the remote or with the on-screen menu) the player will
play the default 2-channel track. (Note: Some players such as the Sony 3000
have a feature to automatically select the first 5.1 track.)
Dolby Digital doesn't necessarily mean 5.1 channels. See 3.6.
