So I'm make this intro cutscene, encode it to OGG, watch it with VLC (no problems) , watch it with Firefox (no problems) , then watch it in FS. And it breaks. It's as if the vid is stretched and skewed diagonally, and the colours are wrong as well. Retail intros, however, play fine.
I used SUPER for conversion (settings screenshot attached) , testing on 3.6.10 official. You can find a piece of it
here - made with the same encoding settings and does exactly the same thing, so this is reproducible. (You may want to turn the volume down before playing this, it's not corrected in this sample.)
