What IS the point of video DRM anyway? I can't remember a single instance of a thing I wanted to watch not being available for torrenting over the years, maybe barring some really obscure television episodes I wouldn't find on Netflix anyway. I do pay for (most of) the content I watch these days (now that I can kinda-sorta afford it), but it's not because it's not available one thepiratebay search away. Mainstream stuff usually comes out within hours of the release.
