MY COLLECTION OF MOVIES: DVD Copy

Surround Format

DTS & Dolby Digital
DTS stand for Digital Theater Systems Digital Sound and is a product of DTS, Inc.,
DTS is a multichannel audio compression format similar to Dolby Digital/AC3 used in DVD-video discs, DVD-audio, 5.1 channel audio CDs, and some movie theaters. DTS differs from Dolby Digital in that it generally uses higher data rates and many have the opinion that DTS is better quality. DTS can only be on a DVD-video disc if accompanied by a Dolby Digital or LPCM track (for North America ) or mpeg audio and LPCM (European Community) to ensure compatibility, because DVD players are only required to decode those standards in those regions.

AAC
AAC stands for either MPEG2 Advanced Audio Coding or MPEG4 Advanced Audio Coding.
The MPEG2 audio-encoding standard of the format is not backward-compatible with MPEG1 audio. MPEG2 AAC can produce better audio quality than MP3 using less physical space for the files. MPEG4 AAC can produce better quality and smaller files than MPEG2 AAC. AAC is the audio file format used by Apple in their popular iTunes Music Store.
