Hey. I think I figured it out. It might not be your lab top. It might just be a time line issue. For some reason my project had changed size dimensions and the time line was refusing to output it to mini dv with the new dimension. SO, I copied my project from the time line that wasn’t working and simply pasted it to a timeline from an enterily different project. It worked!!! It might be worth trying in your case also. cheers.
