Thanks for that. I don't have any DVD+RW media handy to be able to
grab that information. The easiest number to remember is probably
4700000000 bytes. If we're under that, we should be covered OK for all
the common DVD formats, just like 680000000 bytes is a safe max for
normal CD ISO images.

Does anybody out there have a DL DVD drive and media yet? The maximum
LBA on DVD+R DL media would also be a useful piece of information...
