The last time i checked ( it was long time ago :) ), player was able
to resize/zoom/maximize even without hardware acceleration. It's the
main reason why "allow_sw_yuv" is hidden - you are not supposed to YUV
when it's not supported by hardware. It must be a bug.
It is strange that you don't have hardware acceleration with a G450,
maybe Zdenek can say something more meaningful about it ...
