can I transfer digital copies from one iTunes ID to another in the same household?

Within our family there are only two itunes accounts; mine and my wife's. Somehow we've managed to get some movies imported via digital copy redemption on her account instead of mine, the problem with this is the need to switch between user accounts all the time to see the whole movie library. Is there any way for us to transfer the movies from her account to mine- so they are all listed under the same user account? My thoughts are something like a homeshare for our music, where her purchases and mine both compile our collective library.

Anyone have any feedback?

thank you
