I know there is a discussion on this subject and the discussion centered around the DVD player. Mne seems to be different.
I just started using MEP Pro 2015, and I am getting the "Prohibited" error message when played on my DVD player. I burn the same project on MEP Pro 2104 and it works OK. I compared settings on 2015 and 2014, as far as I can understand, they seem to be the same. And on both I have "NTSC (USA, Japan)" selected. Is this a coding or setting problem? Can't figure it out.
