FreeBSD 7 beahves same. I have 7.0-BETA4 (Dec 13). If I put DVD movie in
and I will get over 16k lines in message under a minute.

If I put a blank CD in and I only get less than ten lines in messages. I
can't wait for someone to fix FreeBSD because that over 16k lines under a
minute is very annoy.
