Control your media better.
The hard-pressed Movie Industry should make more of an effort to protect it's investments in the first place. Instead of plying wares on every available format, why not up-scale cinemas to stream content to screens just like the rest of us plebs? Why not just ditch formats that are so easily copied and prevent the revenue loss in the first place? Make content available exclusively as streams?
Oh, what was that? Most of your revenues are made on formats that are easily ripped, then posted to pirate streaming sites? Well, stop doing it then :-)
TV production is streets ahead of this, albeit with proprietary players but at least their production is protected better and then typically released on viewer ratings when broadcast saturation has been reached.
It's a decrepit old man (industry) shouting at the world. It (Sony, et al) needs new tricks.
