With a hard drive / DVD recorder combination, the same sort of thing
applies.  Record to drive, edit out stuff, make disc.  Only one
generation is used.  The system cuts apart MPEG streams, it doesn't
re-render unless you change resolutions.

Though, with a computer, it is possible to lose more than one
generation.  If you transcode from one digital format to another (any
change, resolution, bitrate, format, etc.), you lose one there.  You
probably will, as the bitrate from a camera is generally higher than
you'll use on DVD, so there's often a re-rendering at some point.  And
if you have to render a transition (fades, wipes, etc.), you lose one
there, too.  The hint, there, is stick to straight cuts.

Another truly painful thing about editing on a computer is that the
computer screen is generally different than a video monitor.  It has a
slightly different frame rate, different gamma, etc.  That's a major
problem, here, where video is 50 Hz and computers are usually 60 Hz and
higher.  You're never quite sure if jerks and flickers are just your
preview, or how the end result will actually be.  Likewise, if you mess
around with video levels, the computer monitor is giving you a wrong
preview.  You'd need to learn how to read waveform monitors to get that
right, or simply leave such things alone (take it as read that your
monitor is wrong, the video is fine, don't tweak it).

In the trade "no budget" doesn't mean zero money, it probably means you
have little money, and that you don't have a preallocated budget.
Putting a DVD recorder, even a HDD+DVD recorder, into a place is cheaper
than putting a computer there.  The rest you need regardless (camera,
microphones, whatever else).

The benefit of standalone video gear is generally that it "just works".
There's no fiddling around trying to figure out what to do with the
software, which of the gazillion options you need or should never use.
No time consuming importing and rendering.

Record to hard drive - real time.  Snip out the waiting around and
goofs, maybe half an hour if you only have a few to deal with (find them
at high speed, few minutes tweaking at normal speed).  Burn your edit
from HDD to disc, ten to fifteen minutes.

My experience, as someone who does editing far faster than anyone else
than I've watched, is that the computer adds an awful lot of time in
editing (it's cumbersome without a decent edit controller), and so does
rendering (it's not uncommmon for rendering to take half the time of the
final production).

But, if you're /that good/ at producing a recording, in the first place,
that you don't need to edit.  And you're an organisation that sells off
quite a few copies of your recordings.  Having a bank of five DVD
recorders patched up to your camera means that you can record live, and
distribute several discs straight away.  I've seen churches that do that
sort of thing.  The operators need to know little more than how to start
and stop recording.
