@Coytee I won't get into the ripping/extracting side of things (so as to not run afoul of any potential copyright issues), but assuming that it's already properly extracted etc., you can use tools like tsmuxer (a demuxer or demultiplexor) which would then separate the individual streams (video, audio tracks, etc.) apart into individual files. If I recall, Blu-ray files are normally packaged in mt2s files. In this case, it'd be the video track, audio track, and any other items. It'd be similar for DVDs.
