I think I've managed to get my gstreamer plugins to match yours but without
gstreamer-plugins-libav I do lose x264 and 5 capabilities though reinstalling
it and removing gstreamer-plugins-ugly-orig-addon doesn't lose MPEG-1/2
capabilities. I'm wondering if gstreamer-plugins-ugly-orig-addon is even
necessary.

All the rest of my gstreamer is up to date from openSUSE, I also have a number
of gstreamer-0_10 packages which I can't remove yet due to key packages which
depend on it but I maintain most of them so I'll take steps to rectify this in
the near future:

I'm using gst-discoverer-1.0 to test, I assume that this isn't a totem bug.
