What movies are this? Did you install gstreamer0.10-plugins-good, gstreamer0.10-plugins-ugly, gstreamer0.10-plugins-bad, gstreamer0.10-ffmpeg, gstreamer0.10-plugins- ugly-multiverse and gstreamer0.10-plugins-bad-multiverse (and maybe gstreamer0.10-pitfdll if you want to use win32 codecs)? This will get you support for almost all formats but that DVD playback isn't working is a known bug. You could use a xine-based player for this, for example gxine or xine-ui.
