If I recall correctly, it was a licensed system.  Manufacturers paid a
royalty to be allowed to sell VHS equipment, and it had to adhere to
certain specifications.  Some of the more crapper imported equipment,
from certain countries, didn't adhere too well to standards, and
consequently didn't play too well.

For dubbing your own tapes, the simplest solution is to get a combined
VHS player and DVD recorder, or cable two standalone units together.

To copy something that's technically protected (e.g. using Macrovision),
the simplest solution is a separate VHS player connected to a separate
DVD recorder, with a de-macrovision device between them.

Likewise, to copy a tape that's in poor condition, the simplest solution
is a standalone VHS player connected through some black box to repair
the signal, to a standalone DVD recorder.  In the broadcast world, that
black box would be a time base corrector.  In the toy video world,
there's any number of gizmos for allegedly improving the picture
quality, commonly called video stabilisers.

You can use a computer to capture analogue video, instead.  But then you
have the fun and games of capturing sound and video separately.  Made
more difficult if the video is in a very poor condition, or deliberately
distorted with Macrovision.  You may not be able to overcome those
problems within the computer, it would depend on how well your capture
device handles out-of-specification video.  Then you have to go through
transcoding to MPEG, and authoring a DVD.
