I need to check for any possible misinformation. Webdl (Web Distribution) is a file type that is a direct copy of the movie from its online distribution, not from a physical disc, so it's a common format in both legal and illegal downloading. However, since the user might be referring to a pirated site, the essay should be neutral, discussing the technology rather than the legality unless that's part of the required content. Since the user hasn't specified, it's safer to focus on the technology and user experience aspects.
