I’m aware the 2017 Signature Collection Blu-ray (and its 2018 4K counterpart of the same name) fixed Mufasa’s spirit clouds which is why I plan to use that version when I edit that scene someday. Other than that, the 2017 version seems identical to the 2011 Diamond Edition Blu-ray

As for the 2003 audio, I’m not sure as DVD audio is usually compressed (especially in stereo) and I want to use lossless sources in terms of audio in both Stereo and 5.1 surround (I’m aware there’s 7.1 but that was never in the theatrical version and was added to the 2011 Blu ray and 2017). Unless you provide me proof either the stereo or 5.1 surround options of the DVD version are lossless, high quality, and match the original theatrical sound mixing, I have no plans on using any DVD audio for the movie.
