| 536 | Internally the buffers of the PVR350 are always set to 720x576. The |

| 538 | this buffer. For any video which is not 720x576, the buffer will |
| 539 | then be cropped to remove the unused right and lower areas, with |
| 540 | the remaining image being scaled by the hardware to fit the display |
| 541 | area. The video can be scaled both up and down, so a 720x480 video |
| 542 | can be displayed full-screen on PAL and a 720x576 video can be |
| 543 | displayed without cropping on NTSC. |
| 544 | |
| 545 | Note that the scaling only occurs on the video stream, the osd |
