Unfortunately, I haven't been able to discover any information online as to where those 3 volumes originated and who compiled em. I've listed as much information as I could discover on every clip in the compilation, including where the episode starts in the longer movie scene, how lengthy the short episode is, who it's directed by, a relevant link, information on language and subtitles, and (where I could discover it) information on the video's content.
