They're not in an exact order, so my advice is to save them in order yourself -- maybe on youtube playlists a few chapters per playlist (They can be rearranged if saved out of order), or bookmark them by chapter(s) in folders.
This is simply awesome! =D
If someone does make youtube playlists, and if you don't mind sharing, please leave a comment and a link!
That would be wonderful! =)
