According to Adam Wilt's hierarchical list of video formats
(http://www.adamwilt.com/DV-FAQ-tech.html) DV is higher
quality ("9") than 3/4 SP ("6.5"). Therefore, dubbing from 3/4
SP to DV will preserve all the quality you can squeze out of
the tapes (and the player).
OTOH, video DVD is significantly lower quality than 3/4 SP
(I estimate between 3.5 and 4.5 on Adam's scale). Therefore,
you would be losing a significant part of what is on your tapes.
But running off a convienence/reference DVD on a standalone
recorder while capturing to DV wouldn't be a bad idea, IMHO.
Perhaps someone would like to take a stab at placing H.264
on Adam's scale for reference?

Not clear why you would want to destroy the tapes unless you
really don't have room for them or something? Is the content
(undisclosed) something that a library or a historical society
might be interested in?
