This was covered about a week ago in questions.
I had similar problems and am not at all sure why or that the
changes I made fixed the problem, but it now works for me, at
least for the ISOs I have made in the last couple of weeks.  I
haven't gotten to making my CD backup of my web page yet.

The main thing I did was take out the '-s max' speed parameter and
came up with this which works:
  /usr/sbin/burncd -v -f /dev/acd0 data FreeBSD62-disc1.iso fixate

It makes a both bootable and mountable CD.

Although I have used -s max successfully in the past, burncd
stopped working when I went to FreeBSD 6.xx - could neither boot
nor mount the resulting burned CDs.   Taking out that parameter 
seemed to get it working again.

Maybe, at least sort of??   
Or is it my CD burner getting old?
Except the problem showed up on all of the machines that
I brought up to 6.xx.   I doubt that all their Cd burners would
simultaneously die at the same time.   A couple are barely used
and I don't really stress my main one all that much.
