Any one.

rpm -e filename.rpm

I guess you need to uninstall the file by its exact name, the name can be found from
'rpm -qa |grep replayer' then erase the file by 'rpm -e xxx.rpm' where xxx is the output list of the first command.

If you like to install the module indvidually, you may try 'rpm -i --nodeps xxx.rpm' which means install each module without worry about the dependency

For RedHat, Fedro users, there are some easy ways to install packages by using apt4rpm
like the 'apt-get' tool in Debian, but first need to install all the apt4rpm modules manually.

Hope it helps
