Like most animation, My Little Pony: Friendship is Magic is produced at 23.976 fps. Because of TV format restrictions, though, it's converted to 29.97 fps for broadcast on TV. The process is (usually) easily reversible, letting you recover the original 23.976 fps content, and requires all of one plugin and two filter calls in an AviSynth script, and a number of more automated encoding programs can also do it. This is one of the most basic parts of encoding TV and DVD sources for viewing on a PC. Yet every single rip of the first two MLP S2 episodes I've found has been left at 29.97 fps with every fifth frame being a duplicate or, worse, two out of every five frames having a ghosting effect on moving parts of the frame.

Even among crappy fansub encoders, only the worst of the worst manage to completely fail at this.

Edit: Okay, screw the TV encodes — iTunes has S2 episodes now. The colors in them are screwed up, but at least that can be fixed with post-processing in ffdshow.
