In the future, post threads asking for help in another forum such as "General Support", note the heading of this subforum:

To install the software in the tarball, you first have to untar it. This can be done from the GUI (right-click > Extract all) or from the command line (Applications > System Tools > Terminal).
If the extension of the tarball is "tar.gz" use: tar -zxvf filename.tar.gz
If the extension is "tar.bz2" then use: tar -jxvf filename.tar.bz2
Now your tarball is extracted, change directory to the untarred folder with "cd":
To change directory: cd filename
In the folder, look for a README or INSTALL file, this might have specific instructions on how to install it. If there is none, then run the following commands to install it:
./configure [You may encounter errors here regarding the presence of certain dependencies that must be installed for the software to work, you have to install these before going further.]
If all goes well, your program should be installed and ready to use! Note that the best
way to install stuff is with yum, which will take care of all the deps for you.
EDIT: Again just ahead of me ah7013
coolmego, as mentioned before I recommend you install it with yum. However Dave has put together a tarball of VLC and it's deps, just download the tarball, untar it, and run
yum -y install *.rpm --nogpgcheck --disablerepo=*
