If you spent a quarter of the effort actually answering the question posed -- Like Mara was able to do -- and not googling "maemo extras-devel mplayer" (whatever the heck that is) this would be a more useful site. Mara was able to explain -- in clear English no less -- and even did so without the cute use of the word "hint."

I suspect a rock is out there somewhere waiting for you to crawl back under it.
