openSUSE as packaged by Novell/SuSE-GmbH is crippled for proprietary audio such as mp3. The nature of the crippling is such that just removing an application is not going to provide the needed codec. Hence removing the Novell/SuSE-GmbH packaged libxine1 will not accomplish what you seek. A better approach would have been to replace the Novell/SuSE-GmbH packaged libxine1 with a Packman packaged libxine1.
