It is more helpful to explicitly state what you are

Do you already have a website to host it?

Can you break it up into logical "chunks" that are
small enough for YouTube?

You don't need high quality (or maybe you don't
need video at all?) for a "talking-head" lecture.
If it is something very finely detailed you need a larger
frame size, or if it is very fast-moving, you need higher
bandwidth to maintain some minimum pracical quality
level. Either larger frame size or faster frame rate directly
translate into larger files

So are these inherently PC-centric or Mac-centric

That is a very sticky wicket and it is rare that it
can be done satisfactorily.
Can the demonstration be re-shot properly?
Is there something compelliingly important
about this presenter or this presentation?

Except that apparently it doesn't sound very good.
And transcoding it from the MPEG on your DVD
to yet another video compression codec will only
make the video worse.
Do you have access to the original 8mm (or the
VHS dub)? As you have already noted, the farther
you get away from the original the worse the video
and audio quality will be.

OK, if a friend made it at home, it is not encrypted.
If you buy a commercial DVD of a Hollywood movie
(for example) it is encrypted to discourage piracy, etc.

Many of your decions are based on practical, economic,
and aesthetic matters that only you can decide.
Is the general quality of YouTube adequate for your
content? Its convienence and especially its cost (i.e.
free) are extremely compelling in arguing that is likely
your best bet. It would quite possibly be worth the
effort breaking up the original video into "chunks" in
order to take advantage of YouTube's hosting and
distribution. Given what you have told us so far,
and given your apparent level of experience.
Could you possibly prevail on your friend who made
the DVD to upload the video to YouTube instead?
