YouTube got in trouble because they were knowingly making money from infringing content. Viacom sued them for a billion dollars and YouTube barely won on a technicality. ContentID was a way to get copyright holders off their backs. If you're not sending internal memos about how all of your money comes from pirated blockbuster movies, the DMCA safe harbor makes things a lot easier for you as a service provider. You'll need an automated way to take down videos and forward complaints to uploaders, and an automated way for the uploader to say they're challenging the complaint. After that it's between them, and won't involve you until you get a court order when the uploader loses the lawsuit and is forced to remove the video.
