Most of these types of photos are shot by US Navy photographers, and as they are then government employees, their work ends up in the public domain. If you google something like: VF-8 June 4 1942, you'll find the same images are on Pinterest, and some other sites. The guy who made up the DVD you own also them put them on his disk. "No harm, no foul," as the expression goes.
Where things might get "sticky" with the law is if you actually had posted images from that DVD here. While the images themselves are in the public domain, that DVD is likely coyrighted. So, a lawyer with not much better to do might then be able to claim you violated that copyright because you took the images specifically from that copyrighted disk. I am not a lawyer myself, but this is why we have them, and this is the type of work they do...argue arcane little points of law. Good thing you then did not post your images!
I actually enjoy searching the net for stuff like this. The credit here properly goes to Bob below. He suggested looking for the Hyperscale thread. I did not find that, but found another thread which provided the website I have linked. I hope they do indeed help with the discussion.
What I have yet to try is Wade's suggestion below...go to the John Ford movies. They are available on Youtube. The Midway movie is about 18 minutes long. Not sure about the VT-8 movie. On Navsource is a still frame from Ford's Midway movie:
If this is indicative of everything to be found on the film, then it will not prove too much. However, I have not seen the whole film, so hopefully there is more/better evidence.
At the moment, I personally don't see any evidence for any deck markings on Hornet at Midway, but not all the available evidence is in yet. What I can say, though, is that in "about 2 seconds" I found clear evidence of markings on Enterprise. Check this image:
It is the fifth photo down on this page:
Yet, in all the hunting so far, I can't say the same for Hornet. In my opinion only, it is not looking too good so far.
Hope for more contributors...the more material we can gather, the better off we are!
