Thanks mate. I read the link but it doesn't mention anything about whether I'd lose my films purchased from iTunes.Yes, you can change the email address of your AppleID. I did it years ago with no real trouble.

I'm not sure if changing the iTunes user name will sever the MA/iTunes link. However, even if it does you will not lose movies that have already transferred (see here). Obviously new purchases will no longer transfer if the link is broken, and you may have to wait for 180 days before you can connect an account with a different user name to MA. But I suspect the MA support may be able to help you out if you explain the situation.If you are knowledgeable about Movies Anywhere (MA), do you know if UV codes I used on MA will be deleted?
I will contact MA just to make sure.
Thanks Rigby. I got confirmation from MA that existing films will remain.I'm not sure if changing the iTunes user name will sever the MA/iTunes link.
