523 | this buffer. For any video which is not 720x576, the buffer will | |
524 | then be cropped to remove the unused right and lower areas, with | |
525 | the remaining image being scaled by the hardware to fit the display | |

527 | can be displayed full-screen on PAL and a 720x576 video can be | |
528 | displayed without cropping on NTSC. | |
529 | ||
