Who really cares about DMCA? If you’re copying discs you bought and aren’t sharing those copies, who would even know you did it? I view it as more of a way to theoretically throw the book at someone caught sharing than a way to imprison people who make personal copies.

Downloading is a "grey-zone", but no one that I know of got in trouble for that. Uploading is not allowed, and the little seeding done while downloading a torrent is still illegal. Although getting in trouble is rare because ISPs are not allowed to give out user data to random companies.
