Can't speak to other countries but I know in NZ you're not allowed legally to rip DVDs or blurays you own (even just for private use, no distribution intended). The copyright act is structured with a whitelist of permissible format shifts, and while CDs made it onto that list, movie discs didn't.
Surely you can still resell and loan the physical CD/DVD though, which is what's being discussed here as universally legal? I think ripping DVDs would be seen as equivalent to photocopying a book.
This is true in America as well, though nobody cares. DVD's and bluray are protected with DRM, and you can only legally circumvent that DRM to use a short chunk as a critic or to develop accessibility features.
I am unaware of anyone prosecuted for ripping though, only several for developing/spreading the DRM circumvention.
Though, the other poster is right, that's a separate thing to what is being discussed.
