I want to test my understanding of how an AM-21n works.
I'm in zip 75605. The AM-21n loads up the channels I want, mostly; but it does not load channel 21-3 from Shreveport, LA. That channel ("Movies!") shows old movies. So, I added as a secondary zip 65802 which has a channel 21-3 listed (but not showing the Movies! channel).
Now, the only channel from zip 65802 that is available to me is 21-3 plus of course I've got the channels from zip 75605, my primary zip.
From all of this I conclude that in order for a channel to even be listed in a pick list in a DTv receiver it has to 1) be listed in a zipcode that is entered into the AM-21 and 2) must also have some level of signal strength. Is this conclusion accurate?
To record the Movies! channel I can make manual recordings - I can't use the guide data to do so as it is incorrect, not showing Movies! listings. There are twelve markets in the transponder database that have an OTA channel that is listed that is showing Movies!. Is there any way to encourage DTv to list all of those channels in the database?
