Apparently there was another review of someone reporting this a year ago, and the company replied that they would fix it a year ago, and they still haven’t. Whatever undocumented method it uses to do this, even after changing them back, all the files still show the icon from this app as a nice reminder. This app will take over all associations for video file types without asking, and to change them back you’ll have to manually right click each different file type (avi, mp4, flv, etc etc) choose Get Info, select the app it’s supposed to open with like QuickTime or VLC and then click Change All.
