These are Anime on Demand WEB-DLs from before it merged with Crunchyroll.
You can find these same movies, with the same filtering on German CR, except they're bloated re-encodes of the videos in this torrent (with some detail loss).
Everything presented here (except for The Scarlet Alibi and Movie 10) is dub-only, with forced subs.
Movies are mostly useful for detexting. I don't know how these compare to blu-ray.
My download of German dubbed Movie 10 cut off 4 minutes in, have the full sub version instead.
Movie 18 cut off at 1h13m. It's dubbed but incomplete, I didn't have a download of the full subbed version.
Do share these two if you have them from AoD, as well other stuff I missed:
