It does not work to remove borders when they are in the encoded video,
you have to crop them away forst in that case.

> Another idea would be: Is there a possibility to automatically detect, whether there are such borders in a video, and then don't display these borders on the screen, but "inflate" the video, so that is shown on the whole screen (in the case of being a 16:9 movie played on a 16:9 screen)

-vf cropdetect is for detecting black borders, and when you use -vf crop
to remove them while playing, "inflating" it is exactly what -panscan
should do...

O.T.: You might try the -dr option and see if that makes MPlayer faster
so it can handle some videos it couldn't before...
