Query: Ultraviolet is not welcome.

Warner Brothers needs to stop forcing their lousy UltraViolet digital copies on consumers. Being a Mac user, there was no way to download the UltraViolet copy of Harry Potter and the Deathly Hallows Part 2 when I purchased the blu-ray with the digital copy, and I have refused to buy any other Warner Brothers films that don't offer a viable, download-able digital copy for Mac users ever since.
