bad news...

*pasp* atom data been ignored by quicktime player (almost latest version).

Movie created with command:

./ffmpeg -i /mnt/spool/tmp/devels/voxnews.dv -vcodec dvvideo -pix_fmt 
yuv420p -acodec copy -aspect 16:9 -vf "setdar=16:9,setsar=118:81" -f mov 
-y /mnt/spool/tmp/devels/voxnews.dv.16-9c.mov

*pasp* atom been written with (hSpacing, vSpacing) = (118, 81)

so i think *pasp* atom issue should be fixed first...
