I have little doubt that hollywood movie DVD are authored in exactly the same way I do mine using Adobe Encore. The processes and workflow will, no doubt, be exactly the same.

I do know what s/w each production studio uses but whatever they all use, the principals will be the same. The high end s/w might have some extra features I'm not used to having though e.g. seamless branching for two version of the same movie on one disk.

Your question is a little vague though, are you just looking at a acquiring a list of s/w packages the 'big boys' use or is there more to your question? let us knwo what, exactly, you are after and we maybe able to help.
