It's for the purpose of an install, but the end-user will not be that technically savvy. I think too, that they may have one of those 'minds-eye' dvd with the psychadelic colurs and such. What we dont know is if the content will change over time, or if the need to use the DVD is related to the content providers capabilities. In the end I think it boils down to ease of use to the end-user. They walk in , insert dvd, and press play.

Hope that helps.
