Tod:
That is what I figured...
I am able to do the fix with just deleting a couple of frames of audio. Works properly with the project exported to FCP.
Is there a way (with MPEG Streamclip) to delete the audio that is muxed into the VOB files and replace it with new audio (preferably one piece for the entire 90 minute film)?
That way theoretically the picture would remain as is...
Any thoughts?
