This means that the first DVD reader reported a size larger than the second 
DVD reader did. Maybe the first reader rescued the two lead out sectors at 
the end of the DVD, and the second reader does not recognize them as part of 
the input. See 
http://www.gnu.org/software/ddrescue/manual/ddrescue_manual.html#Optical-media

Ddrescue complains because the sizes do not match. This is to prevent 
accidentally overwriting an image with unrelated data from the wrong input 
device.

If you are sure that the DVD is the same, just give ddrescue the option -C 
so that it can try to fill the gaps.

Best regards,
Antonio.
