For everyone watching regularly the Bitsundso Plus stream, we got a nice utility app made in my spare time to download the current episode as video:
You can download current version here: BitsundsoDownload.dmg
Please try. 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.
