To create a playable DVD, the files have to be put into the master
image (the ISO file, in your example), in order. DVD players are very
simple, and expect the first file at the start of the disc, and the
rest in sequence. They can do a bit of hunting around to play
different files, but each file is contiguous in itself. There's also a
bootblock kind of structure to the disc, with headers identifying the
type of disc.
These are just a few reasons why you use video-DVD creation tools to
create DVDs, rather than try to do it all by hand.
Supplemental:
The creation tools just directly make an ISO file, they don't have to
loop mount anything. You only need to horse around with loop mounting
if *you* want to see the finished ISO file as if it were a disc that
you'd put into a drive. There are various software players that will
just play the ISO file directly as if you'd loaded a disc, too.
What tools would they be? That sounds interesting.
