524
525 Internally the buffers of the PVR350 are always set to 720x576. The
526 decoded video frame will always be placed in the top left corner of
527 this buffer. For any video which is not 720x576, the buffer will
528 then be cropped to remove the unused right and lower areas, with
529 the remaining image being scaled by the hardware to fit the display
530 area. The video can be scaled both up and down, so a 720x480 video
531 can be displayed full-screen on PAL and a 720x576 video can be
532 displayed without cropping on NTSC.
533
534 Note that the scaling only occurs on the video stream, the osd
535 resolution is locked to the broadcast standard and not scaled.
