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? >Depends on the drive.

I guess the CDR blanks are only five bucks or so...
