I'm glad about that.
Theory background:
The difference towards recovering the sessions by
readcd is that they got re-interpreted by xorriso.
So a single session emerged with superblock at address 0.
If the media content was retrieved by readcd, the
resulting disk file would still have the multi-session
layout, but the operating system would have no clue
where the superblock is.
This it would learn from the media's session and
track structure. But not from a disk file or from
overwriteable media types.
A user can examine that structure of multi-session media
by
dvd+rw-mediainfo
or
xorriso -toc
Usually the start block address of the most recent
(complete) track would be the number to use with
mount -t iso9660 -o sbsector=<number>
on the disk file copy.

Oh.
To Eric Wanchic: Do you reboot as rarely as i do ?
Have a nice day :)
