I notice that the 'Connected to" option seems to have disappeared from the Unicable tuner setup page in OpenVIX and I am wondering whether this could have had any knock-on effects. I'm scratching my head because I have transferred my Spaun SUS 5581 Unicable matrix back to my Vu+ Solo 4K, and now the tuners don't seem to see it at all. I don't think I can have zapped either the matrix or the receiver in making the changes, and it has left me puzzled. The matrix is definitely connected to the receiver because its little LED is illuminated (the matrix is powered remotely by the LNB volts). I've tried reinstalling and reconfiguring a few times.
