Crappy PAL->NTSC is easy, you just rescale the image and do simple
field/frame insertions. But you get nasty artifacts like
blinking/shimmering objects (really nasty in starfields in scifi shows)
and text/graphics scrolling is jumpy/jerky. Early "Red Dwarf" episodes
aired on PBS stations in USA used this method. It's really obvious :-(

Good PAL->NTSC is very, very hard. The best ones do image object analysis,
motion detection and frame/field interpolation...
