Yup, that is my experience.

OH, I definitely know they are going to be slow from their age and my
foggy memory of their speed 6X or 8X is very likely their top speed.

OK, thanks for going over this.

I like short command lines.

Is it

SET VOLI=6

or

SET CDR_VOLI=6

>Keep in mind that RSJ creates an ISO for you, under the covers.

OK, I can now, now that you let me in on the secret.
