I have this error message:

Rescued data in mapfile goes past end of input file.
Use '-C' if you are reading from a partial copy.

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


Other differences might occur if a rewritable DVD is used: lseek(fd, 0, SEEK_END) might return the full recordable size if a DVD recorder is used, but not if a reader is used. This might also depend on operating system.
