I have no objection to using DVDRs for handy indexing,
etc. I do it myself. But DVDRs are unsuitable for "archiving"
for two significant reasons:
The nature of the field-burnable dyes has no track record
for real decades-long archival endurance. Indeed, my own
experience is that some discs that I wrote a few years ago
are already unreadable. This does not portent well for ANY
"archival" expectations.
Making "playable" DVDs involves severe MPEG2 compression
which may be fine for distribution or casual viewing, but it
irrevocably discards a significant portion of your video quality
and it is therefore unsuitable for production or archival use.
Granted there are people here who edit MPEG, etc. but they
are mostly removing commercials from off-the-air recordings
of TV shows, etc.

With one DVD per tape, it seems like a very straightforward
way to search for video and the number on the DVD tells
you which tape number to retrieve. Doesn't sound like a
"nightmare" by my definition.

Depends on what you are shooting. You do realize that
you are irretrievably throwing away a significant portion
of the quality of DV by compressing to MPEG.
OTOH, I have the expectation that television viewing
screens will get BETTER over time and that downgrading
my video to MPEG will turn out to be an even more
regrettable mistake when viewed from 5-10-20 years
out.
If what you are shooting isn't worth the $5/hour that
the mini-DV tape costs, why did you even bother shooting
it? IMHO, you are making a very regrettable decision.

You got significant deterioration the moment you down-
graded your video from DV to DVD/MPEG2. No amount of
copying will ever bring it back. But if you are satisfied
with that, there you are. In my world, MPEG/DVD is a
last-step release-only format. It is NOT an archival format.
It is NOT a production (editing) format.

Well, now you have. Good luck.
