Service info - ECM info MOD

Show which CAID, PROV, and ECM PID is being used.

I don't know if It could be done better, or easier, my limited python  knownledge has done this:

Last function of ServiceInfo.py:

	def ShowECMInformation(self):
		from Components.Converter.PliExtraInfo import caid_data
		from Tools.GetEcmInfo import GetEcmInfo
		self["Title"].text = _("Service info - ECM Info")
		tlist = []
		self.ecmdata = GetEcmInfo()
		data = self.ecmdata.getEcmData()
		currentecmpid = data[3][2:]
		for caid in sorted(set(self.info.getInfoObject(iServiceInformation.sCAIDPIDs)), key=lambda x: (x[0], x[1])):
			CaIdDescription = _("Undefined")
			extra_info = ""
			for caid_entry in caid_data:
				if int(caid_entry[0], 16) <= caid[0] <= int(caid_entry[1], 16):
					CaIdDescription = caid_entry[2]
					break
			if caid[2]:
				provid = ""
				if CaIdDescription == "Seca":
					provid = caid[2][:4]
				if CaIdDescription == "Nagra":
					provid = caid[2][-4:]
				if CaIdDescription == "Via":
					provid = caid[2][-6:]
				if provid:
					extra_info = "provid=%s" % provid
				else:
					extra_info = "extra data=%s" % caid[2]
			ecmpid = "%04X" % caid[1]
                        if ecmpid == currentecmpid:
				tlist.append(ServiceInfoListEntry("\c00??;?00*** ECMPid %04X (%d) %04X-%s %s ****" % (caid[1], caid[1], caid[0], CaIdDescription, extra_info)))
			else:
	                       	tlist.append(ServiceInfoListEntry("ECMPid %04X (%d) %04X-%s %s" % (caid[1], caid[1], caid[0], CaIdDescription, extra_info)))
		if not tlist:
			tlist.append(ServiceInfoListEntry(_("No ECMPids available (FTA Service)")))
		self["infolist"].l.setList(tlist)
