I've had a look for the answer to this, but to no avail 
Will my existing iTunes movies be upgraded to iTunes extra? I have a few movies, such as Wall-E, that have been purchased from the iTunes store and just wondered whether this will be upgraded to the iTunes extra format (as was the case for iTunes plus....for a little charge of course
)
I'm sure, knowing Apple, the answer to this will be no. But, it's worth a question
