[jitter] Re: videoplane distortion on videoplane at 90° Z rotation

thanks Dan , ill try the td.rota slab trick.
i still wonder if there isn t an easier way to do this (?)
what i am after is actually what is showed in the attached patch :

i am working on a project where i need to have the movies mapped on a videoplane keep their original pixel dimension and aspect ratio no matter what the destination dimensions are. so one pixel on screen = 1 pixel in world.
i then want to be able to manipulate that videoplane without it being distorted.

how can i force it not to be distorted ?
