Putting this all together, my response should clarify that "Oblivion 2013 hybrid open matte BD by Mrmovi link" likely refers to a specific version of the Blu-ray, possibly a legitimate release or a non-official one with different aspect ratio options. However, since Mrmovi isn't a known major distributor, there might be concerns about its legitimacy. I should advise the user to be cautious about the source, check for official releases, and mention the legal and technical aspects of aspect ratios in movies.
