All I can say now is that the final render will come in the next week or so BUT then I still need to get to work on the DVD menu and I have never worked with DVD Architect so I'll have to learn how it works first. If you guys have your copies of Renascent could you possibly check some visual transitions and tell me if any of them looked too fast or too slow to you? Thanks!

DVD architect is probably the most user friendly software for that. You shouldn't have much of a problem there.
