Participating D2D Studios with Least Working Titles

I'm sure there's a more scientific way of determining this, but I wanted to gauge your experience. Which PARTICIPATING studio has given you the most difficulty in UltraViolet disc-to-digital services? (Not Disney, not MGM, obviously.)

In my experience, even though Fox is a participating studio, it has much fewer titles in my collection that are D2D eligible.
