If the currently tuned channel is a multistream with 8PSK modulation, attempting to switch to a normal (non multistream) channel with QPSK modulation systematically fails (black screen, no sound).
Switching first to a normal channel with 8PSK modulation works ok; and afterwards, channel switching works corectly again -- until the next attempt to go from (multistream, 8PSK) to (normal, QPSK).
I'm using the "Vuplus DVB-S NIM(45308X FBC) (DVB-S2X)" tuner.
Does anybody have any comments or, even better, a solution?
Thank you.
