Should I allow my mother in law to have a copy of my wedding DVD that she did not contribute to.

My wife and I are married for almost 2 years. When the planning started my mother in law said she could afford a lot of things but really could not.Which is fine! You leave with in your means. One of the things she said she was NOT paying for was a videographer & photographer at our wedding. My parents said, OK that's fine. We will pay for it so the kids don't have to.It was approx $5,000 for both including 3 DVD copies of the wedding and our wedding album. Well its now 2 years later and my mother in law is still working out details on her album but is pushing us/me for a DVD copy of the wedding. My wife is 6 months pregnant and this is putting a lot of stress on her and our marriage. What should I do or say? My wife defends her family and I obviously defend mine. wheres middle ground? How should we proceed
