Open a file description page for an Ogg video file in a browser such as IE11 that does not support WebM or Ogg formats. You see the following message:
For a better video playback experience we recommend an HTML5 video browser.
This is misleading, as IE11 is a "HTML5 video browser" in that it supports the <video> tag. The real problem is that it is missing the required codecs. The message should be changed to reflect this.
