There's yet another problem. Seems there's an API change in the dvb headers 
that causes what you're seeing. Rebuilding against older dvb headers results 
in working channel scanning. I've pinged Axel about it, but no solution has 
been put together just yet.

I believe the main thing that needs doing is some additional backporting from 
trunk to properly work with newer dvb headers, but I've not had time to get 
around to it. I've got a working i386 build (built against 20061107 dvd 
headers), but no x86_64 one at the moment (haven't got an x86_64 box still 
running FC6 handy).
