I'm trying to make a backup of a DVD.

I have the entire project sitting in QT6.0.2 fully synched and looking great. When I try to export, I get the following report from QT:

"Couldn't export the movie "movie.mpg" because a bad public movie atom was found in the movie"

I am trying to export to DV for NLE in FCP, but I've noticed that this message pops up for any type of export.

Has anyone else run into this roadblock? Is this some new devilry in QT to prevent backing up movies? Is there a known workaround?

TIA
