What parameters are you entering for the channel scan? I forget how
it's done (advanced something perhaps) but before you do a scan you
have to enter a bunch of parameters related to the dvb transmission
from your local transmitter.
These are what I used for Crystal Palace.
freq 505833330
B/W 8MHz
Inversion Auto
Constellation QAM 16
LP Coderate 3/4
HP Coderate 3/4
Trans Mode 2K
Guard Interval 1/32
Hierarchy None
I worked these out by following this document
http://www.ethics-gradient.net/myth/mythdvb.html
which showed me how to use scan and tzap, from the dvb-utils package.
BTW I'm using 18.1. I believe there have been lots of dvb related
changes in the SVN version, so things may be different now.
