Regarding iTunes video DRM removal tool, I think TuneFab DRM M4V Converter is the best one, as it really.
The thing is, Requiem only works with iTunes 10.7, which is already a seriously outdated version of iTunes. Even if it hasn’t been updated for several years, it’s still capable of removing Fairplay DRM from Tunes, if you follow the appropriate guide. DRM is intended to protect the content owner and keep e-books.
You can choose if you would prefer not to apply Digital Rights Management (DRM) software to the digital file download of your book.
