I have used DVD Decrypter [0] (unfortunately Windows-only) to make ISOs from DVDs. All the menus are retained, so I can still access special features (image galleries, character profiles, etc.).

I also hear good things about MakeMKV [1], which apparently allows some sort of lossless ripping of video files (I haven't used it, so I cannot confirm this), although the MKV format does not support menus.

I'll second DVD Decrypter. I archive DVDs with that, then use handbrake to pull all the useful bits (the film and special features, or programs in the case of TV series) for Kodi.
