hi, just want to say something, though I'm new here also, i've done what u did already, meaning, u've just added additional medium or source of RPM that u wish to install... try as root at the commandline.. type drakrpm-edit-media and you will see that there's already additional medium besides u'r disk1-2-3... so, if u wish to install additional rpm packages, and its not available with U'r CD's, and its available via contrib, u may able to install that package u wish to install.
