We just completed a total overhaul to our Audio and Video players so that they now take advantage of built in HTML5 support for audio and video. This makes our player compatible with all modern web browsers, including mobile devices like iPhone, iPad, Android, etc. For older browsers like Internet Explorer 8 (which does not support HTML5 video), and Firefox (which supports HTML5 video but is not licensed to play the MP4 format yet), we will still provide the old Flash audio/video player (but with a new skin), so your visitors will not lose any functionality.

The old Flash player will play both the old FLV and MP3 formats (like it used to), as well as the new MP4 format (for progressive compatibility). So for greatest compatibility we recommend using MP4 format for all videos and MP3 format for all audio files. We also recommend converting all your old videos that were uploaded as FLV to the new MP4 format, so that they will be viewable on mobile devices that don't support Flash. But if you keep old FLV files on the site, they will continue to be viewed by any browser that supports Flash (virtually all desktop browsers, but not most mobile browsers).
