While you won't get the same experience listening to Dolby Digital 5.1 audio on a Dolby Pro Logic system, you will notice a dramatic difference between listening in Dolby 5.1 and 2.0. Of course to take the fullest advantage of 5.1 you'd need a Dolby Digital receiver. Put simply, in order to fit all the information on one side of the DVD, the technology utilizes two layers of information. That delay is the laser reaching the end of layer 1 and finding layer 2.

Dolby Pro Logic is a matrix decoder that decodes the four channels of surround sound that have been encoded onto the stereo soundtracks of Dolby Surround program material such as VHS movies and TV shows. Dolby Surround (or Dolby matrix!) is a matrix encoding process that in essence "folds" Left, Center, Right, and Surround channels onto stereo soundtracks. A Pro Logic decoder "unfolds" the four channels on playback (without a Pro Logic decoder, the encoded program plays in regular stereo). See similar questions...

These are all encoding techniques to allow a multichannel signal to be delivered to the consumer. The main difference between them is the number of channels and how the signal is decoded. While Dolby Surround and Pro Logic are closely related (with the main difference being the fact that Surround uses a passive decoder while Pro Logic uses an active one), Dolby Digital is a completely different, more sophisticated technique and not compatible with the others.

Dolby technologies put you in the center of your movie-going experience. You will hear five full-range discreet channels, plus a subwoofer channel that coves the bottom one-tenth of the audible range - these are the technologies that create the experience. The dynamic range (the ratio of the loudest sounds to the softest) is significant and the full-range surround channels make lifelike special effects possible-think helicopters flying overhead.

Most DVD-Video discs contain Dolby Digital soundtracks. However, it's not required. Some discs, especially those containing only audio, have PCM tracks. It's also possible for a 625/50 (PAL) disc to contain only MPEG audio, but so far MPEG audio is not widely used. Don't assume that the "Dolby Digital" label is a guarantee of 5.1 channels. A Dolby Digital soundtrack can be mono, dual mono, stereo, Dolby Surround stereo, etc. See similar questions...
