So if you have installed Centos 5 and want to watch movies, what packages are needed to make this happen?
yum install gstreamer-plugins-good
yum install gstreamer-plugins-bad
yum install gstreamer-plugins-ugly
You should be rockin! Totem will now play your videos without issue. However, I still use vlc media player for my DVDs.
From my research gstreamer still has a little work to do on the DVD menu front, VLC works flawlessly.
