On MacOS, when creating two MediaPlayer instances with one containing H.264 media, the media player state is messed up. E.g.:

  - The state (playing, paused, stopped) is incorrect
  - The playing time events are not sent correctly

It does not matter whether the two media are from different URLs, from the same URL or even the same Media object.

A reproducer is attached (based on the MediaPlayer sample available from Oracle). It shows the problem with two stages having a MediaPlayer and a MediaView each in the following scenarios:

  - a flash media and a H.264 media
  - two H.264 media from different URLs
  - two H.264 media from the same URL

This does not happen when there are two flash videos being used or when only a single MediaPlayer is created.

Running the reproducer on Windows XP with DivX codecs installed does not show this behavior.
