When attempting to playback an MP3 from Screencast.com the following errors may be visible
Screencast does not currently support playing back of mp3 files, so results may vary. Unfortunately many modern browsers are no longer working with the QuickTime plugin and we do not supply a dedicated MP3 player on Screencast.com. Firefox appears to be the only browser that this playback will work on.
