I have created a project in FCP and exported to burn a DVD on idvd 06.
The menu music is there but there is no audio on the project when I play the burned DVD. In the idvd project software audio is there, but not when I burn it.
I have already followed trouble shooting advice of:
Made sure there are no video gaps in FCP
Changed the audio settings on my computer to 44100.0 Hz
Deleted Encoded Assets
Made disc image and burned it with disc utility
I have burned DVDs in the same way for years without this problem.
