Kmplayer
 

can anyone tell me how to install Kmplayer with GUI interface to ubuntu 9.0?

AFAIK, there is no deb available
Download the source from

I already have vlc Player.But it is not working when i double click the file which i need to run.Is there any other player which runs avi or other media files run when double click?

What happens if you double click?
If you right click on the file you can choose which player you want to use
Other players
xine, gxine, mplayer ....

VLC should work though
Any error messages?

What happens if you open VLC, and then open the file?
Do you have al the codecs installed ?

vlc player is working ,but i have to right click and select run with vlc player.

If i double click it opens Movie player ,i think it comes default with ubuntu 9.0.Then it says

"

The required software to play this file is not installed. You need to install suitable plugins to play media files. Do you want to search for a plugin that supports the selected file?

The search will also include software which is not officially supported.

In the options from your window manager you can set the preferred applications

what is window manager ?
i can't remember it?
can you explain how to do this?

in the configuration from gnome or kde or whatever you are using

I am using ubuntu 9.04.
are you mean synaptic package manager?

anyway is not there any def files for other players which you mention like
xine, gxine, mplayer .... with GUI?

The window manager is the grafical user interface, the thingie that you see on your screen
It can be GNOME or KDE or...
see
http://xwinman.org/

They all have a GUI
I really don't understand what you want

anyway can you tell me how to installe mplayer to my machine?
i know that if there is a def file we can install it using double click as we done in Windows XP.

open a terminal
type
or use synaptic
