At this point my list of channels is correct and at least 2 days of EPG 
updates at 2am has run correctly and pulled data. I have no schedule 
breaks in data during this 21 days.

So I'm back to normal here and I will keep monitoring it.

The question is, will these EPG pulls every change my list of channels? 
If my list of channels is used to pull the data, then I should get 
whatever is listed for those channels.  If the channel list changes on 
the upstream service, then I would not get data, but my channel list 
locally should be the same?

I know I don't fully understand the process. I see in the 
tv_grab_zz_sdjson_sqlite setup it talks about 'existing and future 
channels'. So I'm guessing if new channels are added I'll see them. 
Since this rarely happens, not sure I've seen it happen.
