I was actually talking about demo DVDs, you are talking about intro DVDs. Sirquack has one I believe... I have heard different ways of showing them. Some people have 2 DVD players. A nice one for the movie, and a cheap one to play the intro, and then they just time it with a couple of button pushes on the DVD remotes. Most systems will automatically switch inputs if done right.
Other people are using media center PCs (or HTPCs) and they put the whole intro image on the PC and load it up first with the movie DVD al ready to go and switch from the image file to the actual DVD. Others probably have even better ideas as well.
