In the United States, there’s a service called Vudu Disc to Digital. It’s had a couple of various iterations over the years - I think it first started with needing to insert the DVD or Blu Ray into your drive, and now uses UPC codes as people don’t have optical drives. There are various checks to try and make sure you’re not just scanning UPC codes at the store (location needed to be on). After confirming that you own the disc it is (was?) $2 for SD quality or for $5 you could take a DVD and get an HD version. The catch is that the movies were then added to your Vudu account - not as unencrypted DRM. But, if they were Movies Anywhere eligible, they showed up in your Apple, Google, Amazon, and Microsoft accounts. From there, getting an archival copy is an exercise for the reader. It didn’t have all the movies. And not every movie was eligible for Movies Anywhere. But, it did work for about 60% of my hundreds DVDs when I went all digital. Plus, this method was clearly legal in the United States, so long as you used your own discs and didn’t make archival copies. The rights management must’ve been a nightmare.
