I understand that you have a slow connection, but you might still want
to consider doing a network install of Debian (Etch or Sid), using an
installer floppy set (3 floppies, last I checked) or an installer CD. Or
if you expect to do many installs, download a current set of isos and
burn your own DVDs.
Since your main interest is video, you'll (probably) want to add in
packages that are not officially part of Debian (like mplayer/mencoder
and various codecs), and you pretty much have to do that online, from
unofficial repositories. Also, you will probably be happier with either
the Testing (Etch) or Unstable (Sid) version than the Stable (Sarge)
version of Debian; maintainers are very conservative about updates to
Stable, far too much so for bleeding edge uses like video, where things
change rapidly.
This would also give you the advantage of getting the latest versions of
everything. Even if you stay with Sarge, you'll want to apply its
scurity updates from the onlline security repository (which a sucessful
install will put in your list of package sources).
Aside from that, what you are describing does sound like either a
marginal disk or a marginal drive. Since you've tried two different
drives without success, bad or marginal disks are my best guess. I've
offered some specific thoughts below.
One long shot: are you setting up a swap partition? I've found that some
systems behave funny if they don't have swap, even if it never gets used
in any real sense. (On these systems, when they have swap, I normally
see "free" reporting a tiny amount of swap used, even when there's lots
of free RAM, so I assume it is some weird rounding problem in the memory
mapping.) And installs typically do use all the physical memory sooner
or later, even on systems with 1 GB or more of RAM, because of the way
the kernel does buffering and caching.
Just as a last resort, since you have a DVD burner, you might see if
you can make new DVDs from your old ones. I assume you already know how
to burn data DVDs, using growisofs or whatever you prefer. Getting the
image to burn from is just like a CD:
dd if=/dev/dvd of=/some/path/DVDimage.iso
adjusting the source and destination paths appropriately for your setup.
If you really have bad disks (bad burns, I mean), this too will fail ...
and a successful copy and burn, but an unusable result, probably means
a filesystem flaw in the iso9660 filesystem that the vendor burned.

What exactly does "read" mean here? Do you mean simply that you could
get a listing ("ls") of directories? I often am able to do that with
filesystems (usually iso9660s; occasionally bad ext2s) that are
otherwise corrupted. Getting a directory listing does not mean you have
a good image on the CD or DVD; it just means that the file with the
directory information can be read. A better quick-and-dirty test of real
readability is an "ls -l" or a "du -s *".

At that point, I wouldn't know if it is a bad burn or a bad drive
(unless I'd been using the drive reliably with other iso9660 DVDs, as
you may well have, given your video activity).

Since you mention the Plextor here, I surmise that your prior try used
the HP. When the same DVD (or CD or floppy) fails on 2 different drives,
I usually infer it's the disk.

Probably not, but the files for the packages you actually want to
install would have to be good. Certainly a bad disk 2 would not cause
the install to fail while it is still using disk 1, to mention the
obvious counterexample to your hypothesis.
Since the disks seem to fail at different points, though, in different
runs, I begin to wonder about a physical problem like smudges or dirt on
the disks. I've seen some discussions online about using polishes and
waxes to make scratched disks temporarily readable; you might look into
that (I haven't tried this myself, though). Or at least try wiping them
clean with the kind of cloth you'd use to clean eyeglasses; that's
helped me from time to time with CDs.
You haven't actually said where in the install process things are
failing. If it happens after you get to the point where the package
manager (I don't recall which one the DVD versions use) has let you
select packages or "tasks" to install, then you could try telling it to
install nothing more at this point. You should have a small but
functioning system, and you can then add packages selectively, by hand.
(This is what I always do myself, just to avoid the package bloat that
the "common tasks" approach generates.)

In my experience, yes. I've had a lot of problems, though in my cases, a
bad or marginal drive seems always to have been a factor ... disks that
were erratic with my old and cheap read-only drive now mount, list, and
transfer content great with my new-this-year read-burn DVD drive.
And BTW, if you got them from the same vendor I saw on eBay, the DVDs
themselves are dirt cheap at $1.95 (not really "pennies" more than
blanks, but still pretty cheap), but there's a modest profit built into
his $5.80 S&H charge.
