Tvheadend

Hello,

I'm running a TVH 3.9.2662 on Ubuntu server 14.10.
My Sat config was wotking well with 3 USB DVB-S adapters.
Now I've juste added a multiswitch 5/8 from Megasat and my VU+ Ultime is working well (so the switch is working well).
But I have no idea how to setup TV Adapters on TVH.

Does anyone have doen this kind of setup in the past.
I saw a thread with multiswitch with 17/8 (https://tvheadend.org/boards/4/topics/13401) but indications inside this thread are not clear for me.

Can anyone help me on this., please?

Thanks a lot.
