Alright bear with me, I'm stupidly green and here's my green question :
Download Knoppmyth and installed it.

Everything going swimmingly with the setup except for the Video Source Section.
I choose a Video Source as ukgrabtv or whatever it is , now if I finish this screen it cannot grab anything. So I tried ukgrabtv alt and this tries to get something and crashes stays at 50%.
I tried Sweden/Finland just to see if I can get a result but no joy.

Now I can't run mythfilldatabase presumably as it hasn't grabbed anything to fill the db with.

So I'm stuck. Apologies if this has been gone over again and again before can someone just point me in the right direction.

All well back to trying in the interim.
