Stan,

Please reply to the "ubuntu-users at lists.ubuntu.com" instead of a
private reply to me.

I'm no expert on cdrecord. Other people may have experienced your
particular problem and solved it - so they could give you the
exact solution you need to solve your issue.

I have not tried using cdrecord the way you are using it.
I do remember reading somewhere that it might be a good idea
to set the speed to "0" to make it more likely all CD readers
can read the CD. I do not use the "eject" option of cdrecord.
I use "dev=0,0,0" not "dev=0,0" though obviously both are
legal and legitimate options.
where according to man cdrecord device=scsibus,target,lun

btw, when I want to burn CDs with audio files, I use mkisofs
first, then I use cdrecord to burn the iso onto CD. I have not
tried your method.

Hopefully people with experience and knowledge of cdrecord will
offer their knowledge and experience.

Again, please reply to the ubuntu-users at lists.ubuntu.com
instead of to me privately - try "reply all" option.
