Add/Remove software is a GUI for yum in FC5.
I must say that my repo were not only not setup correctly, they were empty.
Thee must be some issue with FC5, yet once setup properly either through yum or the GUI everything seems to work pretty well; one day maybe yum will be as good as apt-get....
boh..
A part from jokes, I also found that if you need uncommon packages to be installed, then you better configure some external repos in your yum.conf file. The redhat ones infact will not provide you with much. Definitely you must enable red-hat extras. I found FreashRPMS to be a good repo for other nice utilities (DVDRip, Krusader, rar etc...)
