Query: Will not play on Windows 7 PCs

I bought this to have a hard copy for archiving as well as to be able to make an mp3 version for portability. Unfortunately, while it will play on a standalone Blue-ray player it would not play on any of my three Win 7 64-bit PCs all of which have different brands of DVD R/W drives so it is not possible to do a direct conversion to mp3. Also, this audio CD is made on demand using dye based blank CD-ROM media like we use at home, so its life span will be limited compared to regular audio CDs.
