Just as with the original, it is unclear from the configuration settings, what "you will get" upon choosing a download: a video-only file, an audio-only file, or a video with audio.

With the original, I know have it configured so that downloading a YouTube video delivers an mp4 video+audio and an mp3 audio-only. This is perfect, though I have not the foggiest which magical combination of unclearly worded settings gave me this wonder.

With the new WebFail version, I can not get the same result (video+sound, and audio). But worse, whatever setting I try, it downloads a video fail, then extracts an audio file, then deletes the video file under my eyes.
