Problems with "burncd" - cannot mount result on unix or windows

[UCTC Sysadmin]

Using a Sony CRX850E slimline CD burner / DVD reader
FreeBSD 6.1

I write a single file to the CD and say "-fixate"; the command shows the progress of writing
and then finishes with no error message. Trying to then mount that CD on FreeBSD says "unrecognizable"
and on windows says "maybe disk is blank."

Is burncd broken?
