Okay - just been re-checking the docs. I'm pretty sure I used the
README.cdplus as a guide. I did also notice in the README.multi
"Use the -R flag to add Rock Ridge extensions (this is important)."
I don't have my exact mkisofs command saved, but maybe this will help?

I think this is correct, the -multi does not go on the last burn.
I did it once (from the cdrecord README.cdplus). These are the cdrecord
commands I used (I save them in my .bash_history since I don't use it
enough to remember them - and my CD burner died a while back & hasn't
been replaced yet so I can't test):
cdrecord speed=8 -v dev=0,0 -multi -dao -useinfo -swab *.wav
cdrecord speed=12 -v dev=0,0 -data disk.out
I don't recall if the -dao was important to this. The -swab was
obviously just a swap bytes needed by my burner to do the audio
correctly.
There wasn't anything special I did to mount it.
