What model Panasonic TV? It's unlikely to have a DVB-C tuner in it. Panasonic can barely produce a DVB-T (Saorview) compatible model. Perhaps you were receiving Saorview channels off the cable (acting as an aerial)? The local cable system here in Greystones is still analogue and a scan on a TV with an analogue tuner will pick up some channels - this is an exception, though. All terrestrial broadcasting is digital now and most of the cable systems have been converted. Still don't think you can clear UPC encrypted channels directly on an Enigma receiver. I believe the cards are paired to a specific box.
