Well, I was under the impression that the original poster wanted to
know how to play a "burnt" DVD-R (or +R, etc.) which contained a
large number of .mp3 sound files. Since this isn't a commercial
audio/video DVD, it wouldn't start playing the "movie" (or audio
in this case) as soon as inserted...the unit would know the disc
contained data...but presumably not of what sort. However, IF the
unit was a computer digital drive, and IF there existed an association
for files with that extension...would it not use that application
to open and play the .mp3 sound files?

And do stand-alone DVD players (which often advertise "mp3 compatibility")
recognize and play those files once they had realized it wasn't a
regular audio/video DVD disc...?
