Huh? The OP wants software to rip a DVD. Handbrake is a video transcoder and can't rip encrypted DVDs.
I use DVD Catalyst for most DVDs but since it's no longer actively being developed (I believe the author had legality issues) there are DVDs coming along that DVD Catalyst can't handle so, for those, I use MakeMKV which has never failed me. After ripping a DVD using MakeMKV, I use software such as Handbrake to transcode to mp4 which results in a smaller file that is more portable than an mkv file.
