I hate to say this, but nothing will be done about this issue.
The Immersion sets were released by a (now) defunct record company (EMI) over 5 years ago, and since then, the Immersion sets have not been reissued by Pink Floyd and their new record labels. (Sony in the United States & Warner Music in Europe)
Now maybe Pink Floyd will reissue them some day, or maybe the extra content found in the sets will be reissued in another form (like in an "Early Years"-style box set)
Either way, if any of you have an unplayable "Dark Side of the Moon" Blu-Ray, I can provide you with some of the content in file form.
