i have already talked about both the problem and the first solution , which can set it right when used it from the command prompt , but here is another method if u are opening mplayer from gnome , ... click on the video to be opened and select ' open with other application ' , there select ' use custom command ' , then enter ' mplayer -zoom 200 ' , this will open mplayer properly , the next time u need not enter the whole thing, ....... selecting only mplayer also works, because mplayer automatically generates an alias withing the filesystem . But there is a problem , now suppose if u plug in a removable media , u will have to enter the whole command with the zoom option again , because it is a different filesystem . I am not yet confirmed on this point , have to do a little more testing . But i have not encountered the problem on the same machine when i compiled and installed MPlayer-1.0rc2 . Have to test the whole thing a litlle more to confirm the bugs .
