Tvheadend

Hi all,
i would like to test and see the new feauters of the dvb-rewrite branch.

I checkouted the branch, then compiled and installed without any problem, but i am unable to configure the tuner.

Configurations->DVB Inputs->TV adapters:
when i go to "Universal LNB only" i can't select any Network; my combobox is empty.

It's too early to test the new branch or i'm missing something?

my sistem:
ubuntu 12.10
Hauppauge WinTV-HVR400 (Using the SAT tuner)

Thank you!
