Using the 2160's remote, I went to channels 16 and 34. (Channel 23 is occupied with two sub-channels -- 23.1 and 23.2 -- that are not PBS broadcasts.) I found the following connections:
Entering 16.1, 16.2 or 16.3 displays 2.3.
Entering 16.4 displays 2.4.
Entering 34.1, 34.3 or 34.4 displays 2.1.
Entering 34.2 displays 2.2.
I then set time recordings for channels 34.1 and 16.1. The recording worked on 34.1 (it recorded 2.1); it did not work for 16.1 (black screen; interestingly, on the "Title" screen on the 2160 when that title was selected the information bar at the top referenced channel 2.1 even though 16.1 maps to 2.3).
I then manually deleted channel 2 -- twice. Then I added channel 34; that gave me 2.1 and 2.1. Then I added channel 16; that gave me 2.3 and 2.4; however, I could not then access 2.3 or 2.4 by entering them directly, nor could I scroll to them with the "channel +" or "channel -" buttons. The only way I could get to 2.3 or 2.4 was by entering "16.1" or "16.4". Scrolling up from below 16 didn't find them either -- it went right past. In other words, the channels were there but they were invisible -- you had to ask for them by name by entering them directly in order to get to them.
I then did an automatic channel scan. That changed things again. It ended up giving me 2.1 and 2.2 in the normal progression (I can navigate to them using "channel +" and "channel -") but I cannot get to them by entering them directly. If I enter "2.1" I get 2.3. I can get to 2.1 by entering "34.1". As for 2.3 and 2.4, they now do not show up if I scroll down (starting, for example, at 5.1 and hitting "channel -" I get 4.1, 2.2, 2.1 and then the other lines which are displayed below the channel list). I can, however, now go to 2.3 by entering "2.3" or "16.1" -- either takes me there. If I then scroll up from 2.3, I get 2.4, then 2.1, then 2.2, then 4.1, etc.
I then set four timed recordings, with these results:
Setting to record on 2.1 -- blank screen.
Setting to record on 2.3 -- successful recording of 2.3.
Setting to record on 16.1 -- blank screen.
Setting to record on 34.1 -- successful recording of 2.1.
In summary, I now can access, and do timed recordings on, all of the PBS channels. If I want to watch them live through the 2160's tuner (in order, for example, to take advantage of the ability to pause a live broadcast) I can watch 2.1 on 34.1, 2.2 on 34.2, 2.3 on 2.3 (or 16.1) and 2.4 on 2.4 (or 16.4). If I want to do a timed recording I can do so with the same channel settings. I've stuck a Post-It Note (made by 3M Company here in St. Paul) on the side of the television with a note "To record 2.1, set it to 34.1" and I think that I'm set.
As an aside, our digital televisions, which display the PBS channels in their normal order, also displayed those channels when I entered channel 16 or 34.
Again -- thank you all very much for your research and suggestions. We are now back in business -- at least until TPT makes further changes in its channel scheme!
