If your HR20 is set to "Hide SD Duplicates" and you are using a custom list, you'll have to enter them in manually. Once the HD version comes on, the SD version disappears, taking the selection with it.
Yup that's true. I wish they would fix that bug.
I mean if you had BBCA in your favorites, it should just auto map the new HD feed since it knows the relationship of it with the SD feed for "Hide HD Duplicates" and "Hide SD duplicates" to work correctly.
