How do i install mplayer when it is in the form of
.tar or .bz package?
To be more specific...What are the commands involved?
i don't have a net connection..i don't know how to install yum

is it a tar.bz file? or just a .tar? or what? if its from the mplayer site its probably .tar.bz2

open a terminal window and 'cd' to the directory the file is in. run 'tar -xjf fileName' to extract the file. it will create a folder with the same name as the filename (without the extension of course). 'cd' to this newly created folder and read the README file it includes. it gives you a quick summary of what you need to install it, what options you can use, and how to do it. most programs just require three basic steps:
./configure
make
make install (<-- as root)

let us know how it goes.

Well nadroji don't know the installation procedure for both the formats .tar and .bz .Coz i've both of them in my 'Home' folder but i don't know any command to install such files.
Is this procedure u've mentioned the same for just about any other .tar or .bz file?
By the way it's not a .tar.bz file

no the procedure i described is for .tar.bz2 files. the first step i mentioned (ie the 'tar' command) doesnt have anything to do with actually 'installing' programs. tar is used to extract and/or uncompress files in an archive, such as a .tar file.

if its just a .tar file, you should just have to do 'tar -xf nameOfFile' to extract it.
check 'man tar' and youll see options for how to extract other types of files, ie .gz.
