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

532 | can be displayed full-screen on PAL and a 720x576 video can be | |
533 | displayed without cropping on NTSC. | |
