Yes, I just checked this morning and found out that the loaner DVD is actually Blu-ray. Is a USB external Blu-ray player the best way to go?
What's a good one to purchase?
2. Does your DVD play in another machine?
Need to get a Blu-ray player.

Google won't allow the protection method to be looked up.
I tried a number of times and got fuck all.
If I try this one
dvd casino royale protection method
I get articles describing the ARccOS situation, but that's because
the issue spilled into the public domain (news stories). Helpfully,
I even got a lead to a forum. Which the search for INTERSTELLAR
did not reveal -- there weren't any forum articles at all in ten
pages of google results. Videohelp isn't exactly the "most evil"
of forum sites, and some of the other sites have professional
DVD counterfeiters (make more than a "personal backup copy").
Those might be DIVX copies of a movie, on single layer media.
"Forum Video DVD Ripping Have you successfully backed up the Casino Royale?" https://forum.videohelp.com/threads/264601-Have-you-successfully-backed-up-the-Casino-Royale
*******
There are general comments here.
https://help.ubuntu.com/community/RestrictedFormats/RippingDVDs
"To rip encrypted DVDs, you must install libdvdcss2 <===
the same as you would to play encrypted DVDs (see Playing DVDs).
Libdvdcss2 may not be enough for playing DVDs produced by Warner Bros
(they have a JACKET_P folder as well as a txtdt file). It would require
libudf to be installed on the system.
...
This supposedly bypasses the current copy protection mechanisms such
as RipGuard and
ARccOS <=== Sony malware on Casino Royale DVD
"
The idea is, the DVD can have materials added, which a set top player ignores,
which upsets a computer DVD drive. These include purposeful file system errors
which a computer would honor... and then zip off to the wrong spot.
There were
also "weak sector protections", which may cause the drive to issue an error and dump a sense code.
The only Hollywood DVD I have here, all it needs is libdvdcss2. But
every disc can have something different on it.
I don't remember all the details, but ARccOS I think, leaves something
in the OS. And Sony got caught doing that. It's unlikely they used
ARccOS immediately after that, on new releases.
You can check and see if you have libdvdcss2 using Synaptic. If a search engine won't give you a tutorial, then you have your work cut out for you.

libdvd-pkg - seems to have tools such as wget, to fetch source used
to compile libdvdcss2. Ubuntu can never put DMCA contravention
materials directly on line (from a Canonical site) -- some
indirection is required. Time was, there was a link to a
"website somewhere" for this.
You can see in the list of package files, what kinds of materials it has. Seems to have SHA256 signatures, to check authenticity of the file
it will be downloading.

Any ideas?

1. Do other DVDs play without problem in the computer your DVD won't
play in.
Yes, I just checked this morning and found out that the loaner DVD is
actually Blu-ray. Is a USB external Blu-ray player the best way to go?
What's a good one to purchase?
Looking for best bang for buck (quality & price).
Found a popular internal SATA one that can be installed in my desktop...

Looks like the internal SATA will be the cheaper way to go.
2. Does your DVD play in another machine?
Need to get a Blu-ray player.
More research required!
Research first, waste money second :-)
Make sure the player has playback software.
Many of them are "a drive in a bag".
You at least want a player to "reward" your purchase.
You can experiment with other choices later, once
you've at least seen the movie.
You want a "retail" drive that comes with a
software CD and software to play Hollywood content with.
I've had to drive to the store, and read the CD contents
off the side of the box, because the manufacturer refused
to put the info into web adverts. That's how crappy
the topic of software content is, with optical drives.
In the past, some of the drives came with Nero Lite
(but that's not necessarily a movie player, just for burning).
I got a copy of WinDVD once, in a motherboard box, and
didn't notice until looking in some of the boxes one day.
BluRay uses Java code as part of protection mechanism,
and has key revocation as well. On Monday you can watch
a movie, and on Tuesday it no longer works (and will never
work again). That is what BluRay is like. You can own the
media, it's official legal media, and... it won't play.
On Windows, to play 4K BluRay, you need Intel SGX feature,
which is on 10900K but is pinned off on 11900K and later
ones. The idea is always to have rendering done in
such a way, that a user cannot copy the frames out of
memory. The BluRay may work at HD res, without that.
It's possible some key handling is done in SGX. Or they
do the Java in there. Intel had to pin that off, because
there's an exploit for it.
There might be only one ripping tool for it, and perhaps
nothing on Linux. The details of breaking that, aren't likely
to be public, or for that matter, easily reverse engineered.
The BluRay people are quite proud of themselves.
I don't know what the track record is today, but if you
come to my place, you'll notice there is no BluRay
player. There's a limit to how much consumer-antagonism
I'll put up with. The stories about BluRay cross that line.
You may find threads, where someone bought a drive in a bag,
and now they don't have a movie player to use with it.
Look at a Newegg item, then read the reviews in the
web page, for details of what is missing, or what
bad thing happened.
I would buy a BluRay writer, if I needed to do 100GB backups,
but I don't really want to do that either (cumbersome). The
price has come down somewhat, on the media. At one time,
it was too expensive to do backups on BluRay.
BluRay drives can have three lasers, and high numerical
aperture optics. The feature size is quite small on the
media, and the optics have to get very close to focus.
BluRay can have multiple layers, so the optics have to
change focal point to access those. That might not be shown
here.

Sounds like Blu-ray is more trouble than I want. I think I'll stick with DVD. Same for Windoze. :-)

Try and figure out what you're buying with THIS drive :-)
I can't figure it out. You can imagine some street vendor
selling these in some dark alley.

While this one does list the included software,
and this drive likely isn't as "magical".
