I use redfox.bz software and Taiyo Yuden dvds (CMC Pro) at about 35c each. I go to public libraries and check out as many as they will let me for free and copy those. You can also rip as an image or digital.
This has the added benefit of not sending any of your money to people who hate you and since the disc + your time adds up to $1 if it's a bad movie you can skip it or sell to someone else for more.
