Hello list, sorry to post that again but I'm still curious about it. Trying to display a movie with it's original ratio, I'm using dstdimend and dstdimstart of a jit.matrix. Allthought the size of the display rectangle it provides is smaller than the initial movie, I've got a pixelation effect. It disappears with adapt 1 mode (but this kills the ratio adaptation). thank's a lot for any solution Please, don't give me the scale attribute of videoplane method to do that, This is just a small part of my patch.
