You can download current version here: BitsundsoDownload.dmg
You need to specify the ID and password for the login. Than you specify where the ffmpeg command line tool is and where to store the video file. By default it will be put on desktop. Our tool just performs a login on Bitsundso website, gets the video stream URL, picks the 720p stream and downloads it by running ffmpeg. It shows you progress and opens video file on the end. Settings are saved for next run, so you can just run it every week, when you got the push for the new episode.
We have it in use for years now. With this update Apple Silicon is included and we made adjustments for Big Sur. Great for offline watching.
