So I sit outside the store, stay in the cold winter wind, stupidly tired several other Apps under the 50K/s network, include dvdbackup through Homebrew, which just told me 'Cannot seek DVD device'. I'm despaired after 3 hours trying.The Backup option is only available for Bluray. For DVD, only saving to MKV files is supported.
There is no way to save the menu structure for DVD or Bluray if you are converting the video to MKV files. But MKV files generally take up less space than the "backup" option.
So why ineed wouldn't you support DVD backup..........................................................................................................Any way you need to decrypt DVD before you do anything, it wouldn't take your extra work.
