I'm quite sure that MP3 is not supported. Only MP2,AC3,PCM and optionally DTS are supported.
My understanding is that you're right, except that MP2 was not included in the NTSC spec, and it's somewhat common to find NTSC players that don't handle DVDs with MP2 audio. Unofficially, there are plenty of nonstandard combinations that some players tolerate, and MP3 audio is just one of many.
Right. Now that you mention it... Wikipedia (http://en.wikipedia.org/wiki/DVD-Video) says: |The audio data on a DVD movie can be of the format PCM, DTS, MPEG |audio, or Dolby Digital (AC-3). In countries using the NTSC standard |any movie should contain a sound track in (at least) either PCM or |Dolby AC-3 formats, and any NTSC player must support these two; all |the others are optional. This ensures any standard compatible disc |can be played on any standard compatible player. The vast majority |of commercial NTSC releases today employ AC-3 audio. | |Initially, in countries using the PAL standard (e.g. most of Europe) |the sound of DVD was supposed to be standardized on PCM and MPEG-2 |audio, but apparently against the wishes of Philips, under public |pressure on December 5, 1997, the DVD Forum accepted the addition of |Dolby AC-3 to the optional formats on discs and mandatory formats in |players. The vast majority of commercial PAL releases employ AC-3 |audio by now. -- Tobias PGP: http://9ac7e0bc.uguu.de
