Hacked together another fork https://gist.github.com/itsgoingd/4e6f9b663a825143ebd6997806931e73

• based on the most up to date version https://gist.github.com/elochim-siemasz/64edda44c2fcfc28d6b7eed9f78cd62c
• re-added login support from https://gist.github.com/jasondew/5583811
• tweaked for a slight html change on the site (title images no longer have alt text)

Updated @itsgoingd's version in Apr 2021 https://gist.github.com/lukeholder/64f6a3bbc97c050ddfa605fa4d5dff8c

• Added the episode number to the filename and meta data
• Cleaned up the title format (squish!)
• Download as.mp4 extension
• Removed tags ("Watched", "Free") from episode names.
