Full sized MiniDVD disc reader?

[Kirben]

Can anyone suggest a DVD or Blu-ray drive that is able to read a full size MiniDVD disc?
Specifically a MiniDVD, which is actually a full sized DVD, and won't fit into the lower section of the tray.

I have several Pioneer drives, internal and external, but none will recognise the disc.
I need to find a model that is known to work with these discs, as I would rather not waste more money.

Wikipedia suggests that a MiniDVD is the smaller, 8 cm DVD (as opposed to a normal 12 cm DVD). https://en.wikipedia.org/wiki/MiniDVD

If the disc is a full 12 cm, maybe it is a CD written with the format of a DVD which Wikipedia calls a cDVD (Compact DVD) or a mini-DVD. https://en.wikipedia.org/wiki/CDVD These, apparently, are different than Video CD and Super Video CD.

All this is to suggest you might not have a hardware problem, but a software problem.

It is a DVD boxset set of Jacques Cousteau's Ocean Tales from Citel Video in France, and stated as DVDs on the back covers.
The disc itself is really unusual though, I have never seen this mix of disc before.

That looks like a 8 cm DVD that would fit into the smaller circle of a tray loading optical drive or onto the spindle of a mobile optical drive. But you said it won't fit?

Being from France it'll be Region 2.

The full size section is clear on the back, which can be confusing, a photo of the other side:
