How is DTS-HD Master Audio Suite™ different from DTS Surround Audio Suite?
DTS-HD Master Audio Suite (MAS) is capable of encoding all DTS-HD™, DTS Express™, and DTS Digital Surround™ audio stream types for Blu-ray Disc™, DVD, and DTS Music Disc. DTS Surround Audio Suite (SAS) is specifically suited for standard definition optical media, such as DVD and DTS Music Disc, but cannot produce Blu-ray Disc compatible stream types. Both MAS and SAS include the DTS-HD StreamTools™ as well as the DTS-HD StreamPlayer™.
