A friend of mine has made a movie with only still pictures and music/audio. A few days ago suddenly the program got mute. He doesn't know what has happened.

The sound track is normal, the small green indicator at the sound track works.

No tracks are muted, we have checked the Win XP Volume control, we have reset the program settings to default, but nothing helps. Other programs, like Win media player, works.

He burned a DVD from the project, and the sound was normal there.

Has someone a proposal to solve the problem? We would be very grateful !
