All 3 are digital.
If you want to copy: MakeMKV for BluRays are perfect.
For MiniDV you can use any MiniDV camcorder, they have a digital video out (probably FireWire) then import with a video editor on PC. An old Macbook/Pro is the best with the built-in port and iMove.
Obviously you're right and and literally every commercial* videogame ever released is digital in the sense that it's binary information, and the movies that person was talking about were already digital on Blu Ray.
You can kind of justify it as literally correct if you infer the context of "digital" referring to the method of transferral, rather than the method of information storage - I.e when I bought a game disk from a shop, the game was transferred to me physically on a disk, but when I bought one from Steam it was transferred digitally. Doesn't really apply as much for this situation tho.
(*I almost said every videogame ever made, but I suppose Tennis For Two and some other experimental games ran on analogue computers)
Yes minidv/dv are digital, but they look like tapes and require something that can read them to get them on to a computer.
Also, that setup is a pretty good way to digitize Hi8 analog tapes. And I think you can use some of the camcorders as analog to digital converters of an analog video stream (eg, an attached vcr).
Friend brings over MiniDV camera and a tape, and asks if I can transfer it to a PC.
"I don't know, but we can try!"
It took longer to rummage through the cabling collection for the right FireWire cable than to get it working, plugged straight into the front of a Q6600 box running Windows Vista or 7, with whatever software Microsoft included by default.
Even the tape transport controls worked perfectly from the GUI on the PC.
Old macbook is just a cheap all in one solution with FireWire inputs and software processing g.
And maybe I'm old-fashioned, but the last thing I think when I need to connect up some old gear is "I have just the answer! I'll buy a whole 'nother laptop!"
I mean: They still make PCIe Firewire cards in factories every day -- or at least, they once made enough of them that plenty are still kicking around for not very much money.
And it may be 2025, but they definitely do still make desktop computers (with industry-standard expansion slots, even!) in factories every day.
