Well, this version is better, but we are not there yet.

I performed four tests:
Empty channel database, with and without prefer strongest, without channel movement detection.
Filled channel database, with and without prefer strongest, with channel movement detection.
The number of channels detected was the same in all cases: 94 TV channels and 33 radio channels.
What looks wrong is the handling of channel movement detection:
The screen shot on the left shows the result when prefer strongest is not enabled.
The screen shot on the right shows the result when prefer strongest is enabled.
Notice that when prefer strongest is not enabled, the number of channels updated is equal to the number of channels detected, but this number is always zero when prefer strongest is enabled:

Even if there is no change to an existing channel, the old scanner considers it to be "updated", and so that channel appears in the count of updated channels. Is the new scanner excluding existing channels if they have not actually changed? The disadvantage of this is that there is no indication at the end of scanning of how many channels were found.

This is consistent with the way that the other settings on that panel are not saved between successive invocations of "TV Server Config" . Personally, I think that there would be some advantage to the user if certain of those settings were perserved, but that is a separate work item.

I am not happy about the need to externalise this . How many users will know whether their tuner cards are positive or negative? And what about those users who have a mixture of cards?

Also, I thought that you had decided to use signal quality as the determining factor, and not signal strength? Is it the case that signal quality can also be on a negative scale (0% quality = -100; 100% quality = 0)?
