Checked it out. From the posts it is still inconclusive.
So far as jigdo is concerned I have the isos and the md5sums all match the 
source. This is about verifying the burnt cdr.

So far, the only reliable technique I have been able to find is to do it file 
by file. 

That is easy if you have no subdirectories on the cdr, but gets a little 
messy if you do, the files have to be piped to md5sum from find and xargs.

find /cdrom1/ -type f -print | xargs md5sum | cut -d ' ' -f 1 | sort > sumscdr

mount whatever.iso -r -t iso9660 -o loop /mnt

ind /mnt/ -type f -print | xargs md5sum | cut -d ' ' -f 1 | sort > sumsiso

diff sumsiso sumscdr

Not sure if the sort step is really needed.
