Miles, I'm just looking for what Makemkv already does, which is take dvd's and create a single mkv files that retains all the dvd features like the menus, subtitles, and commentary tracks. I would get Anydvd only for those dvd's that makemkv might have trouble with the protection. I'd use anydvd to make an iso, and then use the iso in makemkv. I'm not interested in any kind of lossless transcoding or anything. I want to retain the full quality. I'm going to need many more hard drives to fit all of these mkv files. Good riddance to dvd players.-superboyac
If it's predominantly for DVDs that you want it, then
DVD43 is similar, (and free), ie. it's a driver that decodes DVD protection on the fly - nothing else. No creating ISOs, modifying PGC to jump to menu, etc but it will allow other programs to do it, eg. ImgBurn to create ISO, MakeMKV to create a mkv.
Not as updated as AnyDVD but then DVD protection changes very little these days.
Otherwise, I use RipIt4Me for DVD decryption - it uses DVD Decryptor but parses the DVD structure to remove FBI warnings, jump to menu, etc. It can also call DVD Shrink following so that can be used to output an ISO.
