this is something I've never understood about DRM. If I can watch/listen to it I can capture it. Period. DRM is supposed to simply make the barrier to piracy higher so that less people overall pirate.

But this is a total misunderstanding about how piracy works. Someone will take up the challenge of breaking your DRM, and when they do everyone will download it from that person and then each other. DRM is completely ineffective in a situation where a single point of failure means total failure.
