The xine website release note says there are problems with playback with
xine-lib version 1.1.5, so people encountering this may want to check to
see if they're running 1.1.5, and either upgrade to the latest, or
downgrade to 1.1.4.

<snippet from xine website>

18.04.2007   xine-lib 1.1.6   A new xine-lib version is now available.
This is mainly a bug-fix release; 1.1.5 has CD audio and DVD playback
problems and a couple of X-related build problems.
