	Get any QT stream with H.263 inside of it, the real dimensions are CIF
but they grab a 320x240 image and add black borders. The H.263 header
tells CIF size but QT says 320x240 so the QT player knows that it should
render only 320x240 avoiding the black borders.
	Indeed that's why I added the feature to the H.263 decoder so it
returns the dimentions after decoding the first frame, so the player
could render things right.
