You still haven't explained what the problem is.
What EXACTLY do you do? What do you exact to happen? What does happen instead? What do (or don't) you see? Any messages?
I wrote it at the beginning. Did I not make myself clear? What do not you understand?
I added 2 DVB-T2 module.
Now I have 1 module DVB-S (A) and 3 module DVB-T2 (B-C-D).
I can't understand with managing the 3 modules DVB-T2 to be able to record 3 different programs (channels) at the same time.
