lock tuner tip same canal...

This is beacuse you are looking the "transponder Info" screen. If you look at frontend info screen you will have Dvb-S.
So thi is easy to fix we have to add code like this:

info.getInfoObject(serviceref, iServiceInformation.sTransponderData)
if self.transponder_info:
	tp_info = ConvertToHumanReadable(self.transponder_info)
	conv = { "tuner_type"   : _("Type"),
	  "system"   : _("System"),
	  "modulation"   : _("Modulation"),
	  "orbital_position"  : _("Orbital position"),
	  "frequency"   : _("Frequency"), ..........

ecc....

But i am not sure to add code to get transponder information only for this little thing.
