All I am asking for is a different file extension and a different mime type and possibly a magic identifier such that *authoring* applications (and authors) can clearly designate this to be a different format, in particular if they include new features. Then a *playback application* has the chance to identify them as a different format and provide a specific parser for it, instead of failing like Totem. They can also decide to extend their existing SRT parser to support both WebSRT and SRT. And I also have no issue with a user deciding to give a WebSRT file a go by renaming it to .srt.

  FWIW, I agree with Silvia that a new file extension and MIME type make sense. 

  Keeping them the same won't help applications that don't know about WebSRT, they will try to play the files and aren't likely to deal with the differences gracefully. Keeping them the same also won't help new applications that know about WebSRT, it won't make any difference if there is one MIME type or two.
