+ this buffer. For any video which is not 720x576, the buffer will
+ then be cropped to remove the unused right and lower areas, with
+ the remaining image being scaled by the hardware to fit the display
+ area. The video can be scaled both up and down, so a 720x480 video
+ can be displayed full-screen on PAL and a 720x576 video can be
+ displayed without cropping on NTSC.
+
