When trying to update xine-lib, the following is returned, how did I break it? Please advise. Thanks in advance. Missing Dependency: libxine.so.1 is needed by package xine-0.99.6-1.el5.rf.i386 (installed)

you didn't break anything, it's a repoforge issue (note the .rf in the package name). In the future please report such issues on the repoforge mailing list rather than here.

This particular issue is known but not solved yet, you can track it here: https://github.com/repoforge/rpms/issues/179
