I am not sure I understand the call signs of these stations. Let me give an
example.  Channel 7_3 in MythTV Channel infor is LAFFTV.  In HDHomeRun
(under windows) it is also LAFFTV. In Schedules Direct it is KGODT3  and
the channel that overwrites it is KGOLD3. I think I should ignore the SD

I did hdhomerun_config 10126134 scan /tuner1 filescan and for the above
channel I get two listings
Channel 35 Program 5 7.3 LAFFTV
Channel 7 Program 5 7.3 LAFFTV

That is the problem I always have with scan. I end up with channel 35 and I
want channel 7. According the the repack guidance I am seeing, 7 will move
to 12 and 35 stays put. This will still give ma a problem when I scan. I
think I just rescanned and interrupted it before the overwrite but I am not

So just to clarify, you are suggesting checking that LAFFTV and all the
other channels to check for name changes then just do a rescan and figure
out how to deal with channel 7.

It looks like the repack will move 4 stations we watch.

Channel 35 comes to the back of my antenna and is weak. It has the same
program information as channel 7.
