The nightly builds are bare builds and you will need to scan channels.
As dsayers said, WooshBuid will give you BBC1 HD and all other free to air channels the second it flashes. Feel free to try that and see how you get on.
You will need to follow the H2H instructions at step 3 though, H2H users need to do 3.1 - is it all there in the detructions. But as a test for your tuners it is ideal until you decide if you do a setup guide, a vix image or an OpenATV image, all available on this forum.
Good luck
