<p>I find the easiest way is to find out the multiplex frequencies for your area then remove all the others from the list of transports in the channel editor</p>
<p>Then delete all channels and do a 'scan all existing transports'</p>
<p>Provided the mux frequencies never change, this should be a once only task.</p>

Hi List,<br>
<br>
I hope someone can help.<br>
<br>
My region has just gone through the so-called 'Sigital Switchover', where they<br>
have turned off the old analogue channels, turned up the power a bit on the<br>
digital channels and added HD channels.<br>
<br>
Before this process started, my myth boxes were able to happily scan for and<br>
find the fifty or so available channels without any problems. Now after a san,<br>
it says it is able to find 34 non-conflicting channels and 139 (!) conflicting<br>
channels. It will not insert any of them automatically and will only suggest<br>
incorrect channels numbers for them. When I attempt to go through them<br>
manually I notice that many channels are duplicated.<br>
<br>
I have three separate Myth backends, so I would really like to not have to do<br>
this manually (using mythtv-setup across a VPN is painful). No normal TV is<br>
having a problem re-tuning, so it is logically a problem with Myth.<br>
<br>
I have even tried re-creating the 'Video Source' to try and rule out conflicts<br>
with old data. This did not help any.<br>
<br>
I have also found this bug ticket : <a href="http://code.mythtv.org/trac/ticket/10054" target="_blank">http://code.mythtv.org/trac/ticket/10054</a><br>
I details what looks to be a similar problem but was fixed on 0.24fixes. I am<br>
running 0.25.2. Is it possible that there has been a regression in this area?<br>
<br>
The suggest option on the conflict dialog for 'BBC One' suggests channel number<br>
4169. For those outside of blighty, BBC One shold be on channel 1. All other<br>
conflicting channels have equally incorrect suggestions.<br>
<br>
Attached should be the output from mythtv-setup.<br>
<br>
Is there anything I can do to not have to spend hours manually going through<br>
all of the channels every time I ned to re-tune?<br>
<br>
Thanks in advance,<br>
<br>
