JMF - dúvida

Olá amigos!

Alguem poderia me dar uma ajudinha com isso aqui?
O problema está em doStart () e doStop ()

Estou tentando, após a alteração de
player.setStopTime (new Time(4.0)); // em doStart
e
player.setMidiaTime (new Time(1.0)); // em doStop

fazer com que o audio passe a ser executado nestes novos pontos.
Só que isso não está ocorrendo e eu não consigo ver onde estou errando.
O som antes de um novo start toca normalmente, mas não sai nestes novos pontos.

Agradeço antecipadamente qualquer ajuda.
