I have an HR20-700 and noticed that the "To Do List" contains programs that have already been recorded (and even watched and deleted). What benefit is there to a "To Do" list that contains stuff already done?
I find that there is a benefit to this info. If you ever have a recording that didn't happen as it was supposed to, it is handy to be able to go back and read why it didn't happen. For a time, my HR20-700 was failing on some recordings. It would tell me that someone in my house manually adjusted the recording schedule. This helps me to go to the wife and ask her why she recorded a Lifetime movie instead of the game I had setup. Of course this knife cuts both ways.
