Actually,
There shouldn't be any difference in the picture quality as the PQ will be good, average, or bad, on all instances of the channel, Therefore, it is only necessary to favorite one of the channels. If it's an HD channel, as almost all of them are at this time, it will auto tune to HD, and the signal map will be the same regardless. You should remove more than one instance of a channel from your Favorites List to avoid the duplicates. But whether you use the lower number tier or higher number tier is a matter of personal preference.
The duplicate listings are there in the Time Grid and Search, because some channels are in more than one package level of service and the higher number channels often require a move to a higher level package.
