Go to
easy urpmi and go through the three steps to set up Mandriva repositories so you can install Mplayer with a couple clicks of the mouse.
Step 1: Enter the version of Mandriva you have and architecture, leave the third entry to "urpmi", and hit "proceed to step 2".
Step 2: Put a check in only one box and from the drop down list at the top, try to select a mirror closest to you, and hit "proceed to step 3".
Step 3: Highlight, copy the "long" command produced by the site and paste it in a root terminal and hit enter, this will add the appropriate repository you selected in step 2 and download repository data.
Step 4: When the prompt returns after it downloaded stuff, hit the back button in your browser to take you back to step 2, now un-check the one that's done and check the next one and proceed to step 3 again to copy/paste the command in a root terminal to set up the next repo. Continue till all of them are set up:
main, contrib, non-free, main-updates, contrib-updates, non-free-updates, main-backports, contrib-backports, plf-free, plf-non-free, plf-free-backports, and plf-non-free-backports.
When all your repositories are setup, go to main menu/system/configuration/packaging/install_remove_update_software and look through the directories to see what is all available. To get straight to Mplayer, type: Mplayer in the search field at the top and all packages with Mplayer in the name will be listed, put a check next to mplayer or kmplayer if you like and it will take care of dependencies when you click "apply" to install it. If you have your installation disk as one of your repositories and there is no updates to packages you are installing, you will be prompted to put the disk in the drive to install what you already have rather than download from an on-line repository.
