That is correct. I never tried to demux the file. I just encoded it and set the frame rate at 24fps and never stopped to think that the encoder would do something like this to me :(. It seems that I had blu-ray checked as target playback device when I encoded and this seems to have (once again) applied pulldown on my behalf in the background.

I'm sorry I didn't check that before releasing it. Should I fix it and re-release the file? If that is the case I could just redo everything and take everybody's advice on the NR and try to improve the 720p stream as well.
