Nah, I get it now...
What confused me, initially, is how things got in the to do list...
Personally I think the prioritizer is the the "to do list" and the to do list is "scheduled events" (but I understand that the priority point needs to be driven home, since only 2 things can be recorded at the same time)...
Experimenting, I deleted all from the to do, but still saw the prioritizer notation in the show "info"... Since I did not initially grasp the concept of the prioritizer, I did not understand what I was seeing... I got it now...
It makes more sense when I realize that the "prioritizer" is keeping an eye on the guide for for, so when the next day's guide is acquired, it can keep adding things, logically, not based on a set time and channel... Pretty cool really
OK, I do have one new question... I'll make a new thread for that...
Re-populate the "To do" list? <--link
