I think changing it now will confuse the users
Hurrah! At least somebody sees my point.I agree it is misleading
The only saving grace for not correcting it.The icon was chosen to match what is displayed in the on-screen media list and the logic is mirrored too (i.e. you will always see Enc or no-Enc consistently across the two interfaces).
Of course it's broke! It's just not us who broke it. I would have expected a fellow tech author to recognise the difficulty.'Tain't broke...
