Second SCRpms MythTV Update Attempt

I tried again to update my CentOS 6 x64 system to Myth 0.27.4-30. Now 
all the libraries are already installed from my last attempt, so only 
three packages were pulled in. This time, I rpm -e -nodeps qt47-x11 and 
manually installed qt48-x11 before attempting the upgrade:

** Found 4 pre-existing rpmdb problem(s), 'yum check' output follows:

Complete!

At runtime:

[root@amber ~]$service mythbackend start
Starting mythbackend: /usr/bin/mythbackend: error while loading shared 
libraries: libphonon.so.4: cannot open shared object file: No such file 
or directory
                                                            [FAILED]

libphonon comes from phonon-backend-gstreamer and what I have installed 
is from ATRpms. Should I uninstall that and install the CentOS 6 version 
even if older?
