I almost wish that I was doing something wrong, but I'm not. I downloaded the trial Copy to DVD software like you had suggested, followed the directions meticulously, and burned both my test project , and a second project that I added a simple menu using the VSO software and it worked in every DVD player without fail. So, there must be a problem with the DVDA3 program in where it is leaving something out of the authoring process which allow players to even detect it. For the record when I intially tried to run the DVDA3 versions in my computer they never prompted me for a player. In fact I had to open up my WinDVD on my computer then open the file in my drive to play it. So, now at least I can get a DVD to my clients. I guess I'll edit in Vegas 6, design and save in DVD-A3, and then I'll have to purchase the VSO software to burn. I'll report this to Sony, but if you have any further suggestions please feel free to keep me informed
