How about being able to sort by episode number or better by original date within the program folder? Better because the episode numbers do not always follow the story--who assigns them?
I've gathered a lot of Blue Bloods, Castle, Curb Your Enthusiasm, Dexter, Futurama, Modern Family, Person of Interest, Revenge, The Mentalist, and Monty Python episodes from various sources. Some are in runs but others are rather random on the recording date (catching re-runs) and even network. It makes it hard to follow when you can only sort by date recorded with all the titles being the same. There are more such series, these just some that come to hand.
If you could alter the title (a lot of work) you might sort by that but it all becomes lower case after the initial letter on my 722 and you would lose their folder-ness.
Someday I get to seeing them!
