Does that mean you don't see the files of the first session ?
(If so: Did you really import it into Brasero before burning ?)

Well, isn't it supposed to be a directory ?

What command exactly did you try ?
I'd as superuser
  mount -o sbsector=0 /dev/sr0 /media/cdrom0

While the new session is mounted too, it might be necessary to fool
the O_EXCL protocol of mount by putting a loop device inbetween:

  mount -o sbsector=0,loop /dev/sr0 /media/cdrom1

The superuser will probably not have such permission problems.
I assume this happens during the attempt to find the first CD/DVD drive.
/dev/sg0 may well be a hard disk or SSD and thus associated to /dev/sda.
My sr0 is sg2.

As normal user, try with added option

  dev=/dev/sr0

Contemporary GNU/Linux distros give the desktop user rw-permission to
the /dev/sr* devices via ACL. cdrecord will complain that /dev/sr is
"unintentional and not supported" but will accept it nevertheless.


Be so kind and also post the output of
  xorriso -outdev /dev/sr0 -toc


Have a nice day :)
