Coger videos de youtube con javascript, error en mi codigo! Hola, les escribo con urgencia, pues estoy montando una web que consiste en poner videos de heavy metal de youtube en la web, el sistema que tenia cogia la direccion del flv del video, la enviaba a un reproductor en flash y luego el reproductor la reproducia, todo era perfecto pero el otro dia ya no funciono y creo que el problema es del codigo javascript aunque solo lo supongo, lo que pasa es que no se javascript ademas esta muy desordenado, lo cogi de una pagina web sin modificarlo y no lo entiendo, si alguien me puede ayudar por lo menos a comprender su funcionamiento para ver si lo que hace es coger el flv del video o tiene otra funcion. habra salvado mi proyecto entero, en esta pagina hago las pruebas, pueden ver el ejemplo con videos de metallica: http://usuarios.lycos.es/jflog/metallica.html
Es un archivo llamado SWFOBject:
Y aqui el codigo:
