Once you have ripped the movie  you can use MakeMKV which will rewrap the contents into an MKV file with zero quality loss. It's literally a 1:1 rip so file sizes are enormous. You can use something like Handbrake to compress them, but compression is the devil!
 
EDIT: forgot to mention that MakeMKV will also read directly from the disk, but also works with files you have pirated or ripped and saved previously.
