I suppose you will have to try and see. The "basic" boxes normally just support unicable v1. You are more than likely going to using a Unicable 2 LNB, so in practice that means SCR channels/frequency 1-4 will have to be used for the basic boxes. Double check frequencies in box setup as well as Unicable manual.
Your oscam question may get an answer on another forum. I suggest you keep your thread on that forum to just oscam. The questions about TN800hd should go in a different thread.
