Interesting.  Is it fair to say that if Windows 95 can extract audio CD
tracks from my crappy 4x NEC CDROM (which it can), then FreeBSD can too?
Am I depending on drive-specific application-level code, much as the worm
driver only supports a limited set of CDR devices?

Ugh.  And if not?  Just try a few burns, see what works?  I guess the
CDR blanks are only five bucks or so...

Thanks for the information.
