That is most likely your problem. Either maybe you don't have the XFree86 development packages installed or you don't have framebuffer support, etc.

are you trying to play in X or in the console? if in console then you need to sort out a framebuffer for it to use as the error message suggests if in X try running it like this

mplayer movie.mpg -vo xv

So, what should i do?
Have i to download some packages?
I tried only in console mode, also because if i try to click over a mpeg file in X it say that i have no installed any appropriate program for .mpeg files.
And i do not understand why if i have just installed one.
Probably the problem it's only i am a new newbie.

i wouldnt try to play it in a virtual terminal because it will require properly setting up a framebuffer(not an easy thing for a newbie), so go with X. now while your in X open up a terminal and type 'mplayer movie.mpg -vo xv' and see what happens

I would recommend just getting the Xfree86 development package as trickykid said. If you dont have it on CD then yeah you will have to download it as an rpm. No big deal. It will be called Xfree86 devel though as opposed to development. I had the same problem too and installing that rpm did the trick for me! Good luck.

I installed Xfree86 developing packages but it doesn't works!

The problem now is i don't know what a framebuffer is.

I tried also with: mplayer /mnt/cdrom//chobin/sigla_chobin.mpg -vo xv

Please if you can, help me.
Thank you!!

try -vo x11
or compile it with gui (./configure --enable-gui) and use gmplayer(need to download skins)
