TBS5520SE is not supposed to receive transpondeur in MIS. CrazyCat the author of StreamReaderEx can make this one able to reveive those transponders. This TBS can lock those transponder with CrazyScan and EBS Pro, the issue is only with DVB Viewers.
I think we will not help from TBS...but we can hope.
