Hi,

i see that the advise about the read capacity is overdone,
now that you have a formatted DVD-RW.
dvd+rw-mediainfo will always report the full capacity
of the formatted medium (~ 4482 MB).

For checkreading only the valid range of the ISO filesystem
by dd, you may inquire the size of the ISO image.
E.g. get the byte count by
  isosize /dev/sr0
and divide it by 2048 to get the number of blocks for
  dd ... count=...


Not to forget:

Do not blank the formatted DVD-RW any more.
This would de-format it.

If you want to erase its content for privacy reasons, then
overwrite it by publicly presentable content. E.g. by
  dd if=/dev/zero bs=2048 count=2295104 of=/dev/sr0
(Your kernel should well be able to write to formatted DVD-RW
 without the need for a burn program.)


Have a nice day :)

Thomas
