That test often fails due to a kernel issue, making good media seem 
bad.  I prefer to compare the bits with:

    # cmp /dev/dvd /path/to/iso

If the dvd matches the iso:  if there is no kernel issue there will be 
no output; else it will complain about eof on the iso file.  If the dvd 
does not match the iso, there will be a specific complaint about the 
first mismatch.

Burning and testing all fits nicely into one command line (split here):

    # ( date ; growisofs -dvd-compat -Z /dev/dvd=/path/to/iso ; date ; 
    > sleep 1 ; cmp /dev/dvd /path/to/iso ; date ; echo -e '\a\a\a' )
