Original commit message from CVS:
* ext/dv/gstdvdemux.c: (gst_dvdemux_handle_pull_seek),
(gst_dvdemux_loop), (gst_dvdemux_change_state):
* ext/dv/gstdvdemux.h:
When handling seek requests, don't send the newsegment event from the
calling thread. Instead save it so it can be sent from the streaming
thread.
