+ /* Why can the height be 576 even when the output is NTSC?
+
+ 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.
+
+ Thanks to Ian Armstrong for this explanation. */
