DVD Burning

I have my brand new Shuttle PC setup with a Sony U500 DVD+/-R/W drive. So I worked on my Christmas home video on Vegas Video 4, and ready to try to burn to my very first DVD+R/W with DVD-Architect. Unfortunately it won't work. It is having some programing writing the DVD prep file to the harddrive. So I am installing the MyDVD software that came with the Sony drive and see if I will have better luck.
