You're not. But fortunately, again, I'm not talking about piracy.
Ownership of a video entitles you to a backup of said video by definition of ownership. You don't have to pay extra to get the "digital copy". As breaking disc DRM on legally-owned discs is presently illegal, you need to get said copy in other ways.
None of which have to involve paying extra for something you are already entitled to have.
