Hola a todos, tengo el siguiente problema:
Tengo Studio 9 con parche 9.1.2.15, he realizado y grabado 6 proyectos en calidad DVD sin problemas.
Los últimos tres proyectos que he realizado, una vez acabados los he supervisado antes de proceder a renderizar y grabar en DVD y estaba todo bien y el resultado una vez renderizado y grabado en DVD es que no me reproduce el audio insertado y en su lugar me reproduce el audio original que yo había bajado el volumen a cero y que no se debería escuchar.
Normalmente hago los proyectos de la siguiente forma:
Recortar todos los clip de video
poner transacciones
audio
títulos
y por último el menú
Agradezco de antemano vuestra colaboración
