Scratching My Head, Weak(?) Channels

If you are using a pre-amp, try taking it out of the system or try adding a 3 or 4 way splitter before the tuner to knock down the signal level. The fact that you get the further stations and not the closer ones only reaffirms my belief that you could be overdriving your tuner. While your other tv's may handle the signal quite well, the 722k has a very sensitive tuner.

But, why would I be able to see signal in "Add Locals" on that channel yet, it won't resolve a channel number? Is that a symptom of too strong of a signal?

It sounds like you were having the most trouble with the "Virtual channel" number encoding on the channel, and not so much the channel reception itself. I know I've seen my local stations have times when they were not properly broadcasting their virtual ID, but I don't know that I've ever been able to trace a problem down to a split signal at my end.
Then again, I'm not actually splitting my antenna signal anymore.

I still seem to be having trouble with an overdriven signal on the 2 stations that are 20 miles from me. But, I get all 4 major networks on the stations farther away from me so, I don't guess I can't complain. Well, I can, but I shouldn't.

Hard to peg that one down, since it is possible it could be a channel-specific issue that had nothing to do with your configuration.

A small in-line amp, or amplified splitter, should make up for any loss that's incurred from the split. Your best bet is to place the amp as close to the antenna as possible, ideally right as the cable enters the house. If thats the case, then use a Winegard HDA-100. If you are unable to supply power there, then try an amplified splitter such as the Channel Master CM3412.
Again, glad to see you have your channels working. As you can see, different tuners have different thresholds for how much signal is necessary to register as a channel. Others are more sensitive to signal to noise ratio.
