@DukeNukem, Like @GNUrag said, it's not a good idea to install RPM packages.
Ubuntu has got 3 DVDs of packages available from it's repository!!! I think that's
more than enough for you.
In Ubuntu 6.06 , first get the
Restricted formats, Click
here
Follow the procedure on this page & get it first.
To play MP3, install XMMS:
$
sudo apt-get install xmms xmms-skins xmms-cdread
To play VCD/DVD etc., install MPLayer:
$
sudo apt-get install mplayer mplayer-fonts mplayer-skins mencoder
For a complete list of packages available See my post, 'Unleash the Power of Ubuntu 6.06' Click here
To open Archive files like ZIP or tar.gz etc., just right-click,choose "Open with Archive Manager".
Click on 'Extract', A dialog pops up , again click on "Extract' button.
Simple, your archive file is extracted like in WinZIP!!
