Commercial instructional DVDs often have copy protection or some "pay per
view"
mechanism.   My former work regularly provided instructional DVD's that
could
not be copied.  The software kept a log of the user's progress on the
system disk
and created a certificate file to print on completion, but in some cases we
had to
have the DVD inserted to use the course.

I keep a few commercial DVD's produced by ESA and NASA that
are not copy protected to test DVD readers and software.

Assuming the DVD doesn't reboot into PC-DOS or the like,

Plan A: straight copy to the USB key and see if it is usable.

Plan B:  Windows 10 can loop mount some .iso image files, so
make ISO image file of DVD using dd
<https://www.systutorials.com/create-iso-image-on-linux/> and see if works
in Windows.

Plan C: use the ISO image file to make a "clone" of the DVD.
