I had exactly the same problem after working for days on my production. I had upgraded my Nvidia drivers at the Dell sight to no avail. This morning I saw Larry's posting and followed his advice. I went to the Nvidia sight and got a brand new driver (July '07) and to Microsoft to ugrade DirectX. I restarted then double clicked on my project to start MyDVD and bingo it worked. I was able to burn my project.
