You problem is to mix packages from different repositories. This causes non matched dependencies. As the install if gstreamer-plugins-ugly states it misses a specific library version. The libdvdread package you are hand installing does not provide that one. It is much easier to properly setup repositories using yum. Details are documented within the CentOS wiki and on the rpmforge project site as well. Alexander
