-// Important note about Dolby E parser:
-// Open-Source version of MediaInfo has basic support of Dolby E,
-// created by reverse engineering by an anonymous third-party,
-// with the limitions due to reverse engineering: there is a risk
-// of wrong interpretation of the reverse engineeried bitstream.
-// If you want a safer Dolby E support, based on Dolby E specifications,
-// contact http://www.dolby.com/about/contact_us/contactus.aspx?goto=28
-// for a license before asking it in a specific (and not Open-Source) version
-// of MediaInfo.
