Dumb question first....did you re-sync?
no, I am streaming my content to apple TV... no sync..
Even when you are streaming, the AppleTV seems to want to "sync" data to reflect the changes that appear in iTunes. I have noticed this when I add content to iTunes and/or change tags, artwork, etc. I have iTunes to "Custom Sync" my Movies and TV shows and stream the playback on AppleTV, but this seems to create the situation I've described, that is, a need to hit the "sync" button on iTunes to update the data that Apple TV reports.
I tried that...no change. still showing the "old artwork"
I dont understand why! I clicked "delete" and "add" new artwork. So, in theory, old artwork shouldn't even be there anymore....
can anyone do the same please...change the artwork in itunes and see if it shows the updated artwork inTv?
Is the new artwork showing up in iTunes? If it is, reset the Apple TV and see if the new artwork shows up.
Reset Apple TV:
Press and hold MENU and "-" for about 6 seconds.
