-
-	   Internally the buffers of the PVR350 are always set to 720x576. The
-	   decoded video frame will always be placed in the top left corner of
-	   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.
-
-	   Note that the scaling only occurs on the video stream, the osd
-	   resolution is locked to the broadcast standard and not scaled.
