Practically all recordable media is obsolete for TV: VHS, DVD, hard drives, flash drives, etc. Your recorder is still good for over-the-air broadcasts. I've never used TiVo but I think people are still using it, but that may be too involved for your Mom.
Everything is digitally protected nowadays so if you want it, you need to digitally steal it. There are methods to employ but I don't think it'd behoove my account to explain the options.
What is your Mom's setup...just a DVD player? Surprisingly, Netflix still has a LOT of subscribers for its DVD rental service. It may be worth $8 a month at dvd.netflix.com. According to my Mom, some liberties still freely loan DVDs.
You can still bring your Mom movies on DVDs...you just can no longer make 'em.
