Forcing totem to use xine backend

[Paul Smith]

Dear All,

I have

$ rpm -qi totem-xine

Summary     : Xine backend for Totem
Description :
This package provides the xine backend for the Totem media player.

However, when I run totem, I get in totem's Help --> About:

Movie Player using GStreamer 0.10.19 and GNOME

How can I force totem to use Xine backend?

Thanks in advance,

Paul
