Trying to use gst / omx in python

[TDAS]

Thanks Sebastian. So my import statements now read:

   import sys, os
   import pygst, pygtk
   from gi.repository import Gst, Gtk, GObject

…(it complains if either the Gtk and GObject aren’t also taken from the gi repo). It’s now telling me that gtk isn’t defined… confused!
