It seems since revision 27961 mplayer (when using xv) doesn't scale the video to fill completely the window passed with -wid. It doesn't do initially, but it does after the window has been resized. The problem can be reproduced in smplayer this way: first in preferences->interface set autoresize to "never". Now open a video. MPlayer draws the video on the top left corner of the window using the original size of the video, as you can see in this screenshot: http://img374.imageshack.us/img374/4664/screenshotes6.jpg When the main window is resized then the video actually fills the window as it would be expected from the first moment. It seems this problem doesn't happen with x11 or gl (didn't test directx). Revision 27960 doesn't have this problem. -- RVM
