  This problem has been solved by modifying  libvo/vo_xv.c  myself.  When an
external window is specified  by  -wid  i can make xv act the same way as  "-vo
x11 -zoom -wid" options are used (keep video's  aspect ratio by adding black
borders on top and bottom or on left and right).  And without '-wid' option
everything is the same as before.
  If anyone likes this feature i can make a patch and post it here.
