Glad to hear it's working again, but it's worth commenting that Mike P's 
workaround of installing tuners in a desired order is supposed to be 
unnecessary in recent builds.  There's a real fix, that probably needs 
specific initialisation.  I haven't located a source for this but ISTR 
Mike Dean mentioning it in the last few days.
