Greetings David_Amodei88,
It sounds like you are having issues redeeming the digital copies of your Blu-rays. We know how important this is for you, and you’re in the right place for answers.
The first thing to try is another redemption method. They can be found in this support article:
• Redeem digital copies of DVDs or Blu-rays in the Apple TV app or iTunes for Windows - Apple Support
From the same support article:
If you can't redeem the content code
• Look for an expiration date on the packaging.
• Make sure that you enter the correct characters. Some letters and numbers look alike.
• Make sure that the packaging on your item says that the Digital Copy code will work in your country or region. For example, you need a U.S. Apple ID to use a code from a U.S. DVD, and you need an Australian Apple ID to use a code from an Australian DVD.
• If your Digital Copy DVD, Blu-ray, or 4K title is damaged, scratched, or missing its redemption code or Digital Copy disc, contact the vendor for help.
• If you still can't redeem the code or download your Digital Copy, contact Apple Support.
Cheers!
