If you buy a DVD you have the right, in every sane jurisdiction I'm aware of, to rip the movie from the DVD into an iso. You can then discard/recycle the media and retain the digital copy you have the right to view privately in perpetuity. It is a single consumer license though, as is logical, so it's likely illegal for you to continue to watch the ripped iso if you resell the media with the content still on it or resell the media with any portion of the value coming from the markings from the content or the fact that it used to contain that content. You probably want to shove it in a closet somewhere or just reuse it as rewriteable media for whatever purpose you need - retaining physical ownership of the media makes things simplest legally.

You are only able to do this because the DRM was cracked long ago.

DRM is like a vibe, man - if you have the ability to output a video stream to an arbitrary display device you can always bypass DRM and it's never been illegal[1] to do so (though publishing approaches to defeat it often is).

1. To my knowledge, I am not a lawyer, this is not legal advice.

[Retr0id]

"bypassing DRM" is explicitly illegal according to DMCA. Don't conflate "unenforce{d,able}" and "legal".

[munk-a]

Gosh, I didn't know the DMCA went that far. I had assumed it was in line with Canada's TPM related laws which do disallow direct circumvention of DRM but do specifically except format shifting if the copy will be used for a legal purpose. I guess be careful and check your local jurisdiction.

You don't have that right on the US. The AHRA is the only law which permits format shifting and it only applies to audio.
