[MPlayer-users] -vo quartz overrides movie aspect

Hi -

	It looks like the new "-vo quartz" (so I'm obviously running MPlayer
	on a OS/X system ;)) video output scaling the movie with the 
	screen/display aspect.

	If a MAC has a 'widescreen' LCD such as the Powerbook's 17" LCD
	(1440x900) or the Cinema-HD display (1920x1200) using "-vo quartz"
	scales (and squishes) the movie into a 16:10 aspect even if the 
	movie would fit entirely on the screen.

	For example I have a 480x480 4:3 movie and play it with "-vo quartz" the
	playback window is 778x480 rather than 640x480

	Playing back ATSC HDTV (1920x1080i) gives a 1920x900 image when no
	scaling at all is needed (HD is at 16:9 using 1:1 pixels).

	This feels like the MPEG aspect flags are being replaced by the
	physical aspect of the display.   

	'-vo sdl' uses the Quartz subsystem and does not scale the image (but
	does not do fullscreen - can't have everything I guess ;)).

	Is this a "bug" or a 'feature' in '-vo quartz'? ;)
