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.
