anyone who has the mp4, mkv, or whatever of the show (or any video) can extract the audio using VLC player (free) by opening VLC player and going to the first pull-down menu MEDIA - CONVERT/SAVE. The window opens and you add the video to the list, select the CONVERT/SAVE down arrow button and select CONVERT. Then you get another window to select FLAC, MP3, etc and enter your bitrate and where to save the file output.

then because you might have 1 big audio file - you can load it into any audio editor and cut up the file into each track and save them!
