The software osd layer is too small for HDTV, one has to get larger
buffers for osdP*. I guess that would fix the crashes, but the osd would
not be scaled. To get scaled osd one also has to implement the method
ScaleVUpCopyToBitmap() for YUV modes, which could almost be a copy of
the ones for the RGB modes, but one would have to ensure that
AYUV_to_AYUV420P gets the correct lines.
