Similarly, for ripping movie discs I use MakeMKV; for re-encoding to a reasonable size I use Handbrake with the AppleTV 3 preset, and Video Quality set to 19 for DVD content and 21 for AVCHD/Bluray.
I use MakeMKV because it is fairly easy to use, it rips both DVDs and Blurays, and it’s currently free. I use Handbrake because everyone and their dog whom you ask says that it’s the best for reencoding video files.
