Okay, putting aside the legality (although in Australia there's some provisions for "format shifting"), are you really happy with the "backup" quality provided by most scene groups? I find I can do a better job (at least to my eyes) than most 4.7/8GB movie rips, and the standards for x265 aren't set yet. Ripping your own media gives you a lot more flexibility.
