Most DVD-authoring applications focus exclusively on video DVDs and do not support the authoring of DVD-Audio discs.
This is the primary reason DVD players from different manufacturers do not always behave identically.
Many high-end authoring applications evolve in-house in companies such as Matsushita, Philips, Sony, and Toshiba.
Daikin, a large Japanese air conditioning and refrigeration contracting company, developed Scenarist, a high-end DVD authoring software package.
Like the other high-end and very expensive systems, it conforms to the DVD specifications more closely than other software.
Sonic, a United States corporation, has a major share in the market for selling DVD-authoring tools.
