Be polite and positive.
Don't mention Fox and that whole brouhaha.
Tell them if you have bought the DVD and how many sets.
Thank them for picking up the rights and let them know you are really looking forward to the movie. But don't harangue them about time frames and such.
We want to look like intelligent, rational people, not nutbags! In other words, get the message to Universal, but don't scare the nice people there. ;)
