Here is a fixed version. It supports ass, srt, multiline srt, and trs. See this for the support browsers have for the varying media types. It cannot load local media. On Firefox, you are allowed to load local subtitles, while in Chrome you are not. Also, remote subtitles must be publicly shared dropbox files.
However, if you download the page and open it locally, you can open any local file in either browser, just prefix it with file:///. While you can also load remote media, you cannot load remote subtitles.
For the Frog Prince example, use http://www.axlen.com:80/ab/ohanashi_kaeru_grimm01.mp3 for the audio, and http://dl.dropbox.com/u/263833/ohanashi_...rimm01.trs for the subtitles.
