</div></div>When I was having problems like that here in New Zealand, it was the<br>
LNB settings. I found it very difficult to find the correct settings,<br>
and it turned out that at the time, MythTV had a bug in how the setup<br>
for the LNB settings worked and I had to use SQL on the database to<br>
make it work. So I would suggest that you do a search for the correct<br>
LNB and diseqc settings for your hardware with scan-s2 and see if you<br>
have that right. Once you get scan-s2 working, then try to interpret<br>
the settings into how MythTV sets up the same settings.<br>
