Hi Damien,

Have you tried to do a full scan by yourself using dvbscan instead of 
using the supplied channels.conf from Chris?

Since there was no channels.conf available for me I had to do that for 
myself by building a au-Wollongong file from the frequencies given at 
dba.org.au for my area.

I don't know if this would help but at least you would be doing things 
from scratch to get the channels, I have got SBS with no troubles where 
I am.

With Chris's new changes I didn't have to apply any offsets to channel 
frequencies at all.

Cheers,
Brett
