A boycott is only successful if you know who owns what. Short of selling my HDTV (which would be way popular with my family), I don't see how I can avoid MPAA content.
The harder part, is getting non-tech people to join your boycott. Good luck trying to tell people not to see the new Batman movie when it comes out.
What would be good to know is if actors, directors, and other movie makers support the MPAA's actions. With the RIAA, you could sense that musicians often were at odds with the record companies that signed them. Is that the case with movies? Are there movie studios that don't support things like SOPA and PIPA? Maybe we'd have something if those people (if they exist) spoke out publicly against the MPAA.

But the "content companies" don't only create movies. Now they own large swaths of normal TV. Disney owns ABC which owns ESPN. So every time you watch an advert on SportsCenter, you're funding Disney.
The fact is, you can't win at this game. The way to win is to create an alternate funding mechanism (ie, campaign finance reform and/or owning your own congresscritters). The media cartel owns the (so called public) airwaves.
