I suspect that some sectors are missing at the start such that the size

size of tha DVD?

If the filesystem is ISO-9660 you could try isoinfo tool which is part of genisoimage.

isoinfo -d -i /dev/cdrom

It should list the block size and the number of blocks among other information from the primary volume descriptor of the filesystem
if its available.
