When I looked at the status stream display, I noticed that a switch of channels sometimes results in 2 activities: a "scan" plus the new channel that I selected. When this happens, the new channel fails to tune, or it results in a badly tuned adapter with CC errors.
If there is no "scan" kicked off, the stream tunes correctly, invariably.
Now, I am testing this on Canal Digitaal, Astra 3, decrypted with Oscam via a nodmx connection (mode 4). It also occurs with mode 2.
Could it be that the quick "scan" upsets the decrypt service?
I had reception on RTL7 (adapter 2, 11856V) and switched to Veronica (adapater 2, 12187H).
Why is it quickly doing a scan of 11856V on adapter 3?

Now, when I disable "Idle scan" on 23.5E, I do not see this extra "scan" and the channel switch works.
Of course, I want my OTA EPG, so I've scheduled a mux scan for the relevant muxes at night. Lets see if that works.
