Without going into specifics there are multiple attack vectors for breaking DRM or simply bypassing DRM. Many are unfortunately for content providers trivially easy. The only real limits are for naked, original files which are best possible quality available outside of the content provider networks themselves. Every single transaction point from creation, transmit, transcode/transmux, distribution to CDNs, and finally transmission to the end user is an attack vector. If you're assuming that attacking the DRM directly is the only option or even the best option available, I'm sad to say for content providers, you're unfortunately misinformed.
