first steps in Python without any luck 
im trying add orbital position to channelnames, reverse('2PG') image has it but in compiled \python\Bp>BPutils.pyc without opensource
orbital position can be calculated from namespace or service reference, but i cant get them when ServiceName called under channelslist
/usr/lib/enigma2/python/Components/Converter>ServiceName.py
