Olá pessoal,

Coloquei o exemplo 12 do tutorial NCL3.0 no composer para testar, mas não executa. Quando clico em play, só aparece o controle remoto. Já verifiquei os caminhos das mídias, e estão ok. Não há indicação de problemas (Problems(0)), e no console aparece o seguinte:

JVM v1.5.0 or later...[OK]
Detecting JMF...[OK]
Detecting QT...[OK]
