The problem is in the setting the Media time.
The safety way is to always set new media time with the
following method: setMediaTime(Time time); .... if you want to
use it after
-player.stop(); used as real stop you can use setMediaTime(new
Time(0.0));
-player.stop(); used as real pause you have to use the
combination:
player.stop();
Time currentTime = player.getMediaTime();
//........
player.setMediaTime(currentTime);
player.start();

I found a solution for this problem for those that are interested.
what you have to do is store the time just before you pause and then set the
time just before you play. here is a copy of my pause and play methods
// Start the player
private void play() {
if (player != null)
{
if (pauseTime != null)
{
player.setMediaTime(pauseTime);
}
if (player.getTargetState() < Player.Started)
player.prefetch();
player.start();
}
}
// Pause the player
private void pause() {
if (player != null)
pauseTime = player.getMediaTime();
player.stop();
}
that should solve your pause play problems!
