<https://www.freebsd.org/where/#choose-image>; describes DVD format.

Bug 284666 (too large) was closed as a duplicate of bug 253483 (too 
large for single DVD) which was also closed (works as intended).

So?  Works as intended. A DVD image that can never be on a DVD.

OKay then.

Today seemed like a good day to try an install onto a chunk of hardware
and actually create an installation DVD. I went with the much smaller
disk1.iso image and that works just fine. Maybe the oversized DVD file
has no reason to exist.
