The ISO 9660 file system was designed for a storage medium which had a
fixed capacity of 600 MB.

You're supposed to use UDF on DVDs.  I don't think it's backward
compatible with ISO 9660.  I suspect that the reason why ISO 9660 is
being used on DVDs is compatibility with BIOSes which support booting
from ISO 9660 but not (yet) UDF.
