Very interesting point – I would like to know that as well because there is a “shed-load” of out of date and finished items in my schedule list.
My Enigma 2 DVR has a simple “Clean-up” button! It also stays on the item you have just watched in the playlist so a quick shove on “Red” deletes it without confirmation and if you do change your mind you can find it and re-instate it from the trash folder. The Aura always goes back to a.n.other program in your list, either 1,2 or 3 rows up usually, but if you are not paying close attention and jab “Red” then Enter then your other unwatched program is gone forever – neat! You still have the one you just watched though.
Do the development guys actually ever use their own products? Seems unlikely from the Aura UI disaster!
