Вобщем вроде и работает, но как-то через раз...
Не могу понять в чем причина, ексепшыны не вилетают, все работает.
Но если на строке "player = Manager.createPlayer(Manager.createDataSource(ml));" идет не понятная задержка 5с. примерно, то видео не будет отображатся в jPanel1.
Если запускать через JMStudio, то там тоже какие-то лаги, то есть видео, то розовой экран.
