I think Transponder 19 was already on. The uplink report shows that the channels that were on Transponder 19 were moved to Transponder 16. I don't have Echostar 15 connected to my 622. I'm on the western arc. But my FTA dish sees Echostar 15. The same channels are listed on both Transponder 16 and 19, however it looks like only two channels on Transponder 19 have active video (Palladia and Showtime Too). The rest seem to be slates based on the non-variable bit rates. (All channels are encrypted).
