I've installed it onto a FireTV stick and while the screensaver runs, the video playback is slow and stutters

Obviously coming from Apple, the videos are in QuickTime mov format and I'm guessing that's the problem - the FTV likes h.264 mp4. Any way of changing the addon so that when it checks the download folder for the existence of the file it doesn't pay attention to the file extension? That way I could transcode the downloaded videos and replace the .mov files with .mp4.

Actually I see this on Pi as well. If I play the mov files directly they are as smooth as butter, but there's a difference when playing as a screensaver.
