The last time (a while back I admit) I tried to use ffmpeg's AC3
audio and it didn't play the fellow (not a compatibility lab) mentioned
something about "the rematrixing tables were missing or incorrect".
AC3 is required for North America but I have yet to encounter a player
that will not accept MPEG-1 Layer2 audio. PCM is mandated for everyone
as I understand it - but giving up 1.5Mb/s for audio is usually out
of the question due to space/bitrate constraints.
For DVDs I produce I don't need a "lab" since I'm using a Dolby
certified AC3 encoder which entitles me to, if I desire, place
the Dolby logo on my DVDs (packaging as well as the trailers/credits) :)
Cheers,
Steven Schultz
