Just upgraded to this Ultimate version. Trying to burn a .VOB movie file. I put in a Pro dvd as the burn medium. When I clicked on burn now the following message appeared. error: Too big file found in the project ( bigger than 2 GB ) The file size is only 2.8 GB. I converted the original movie from an .avi file to the DVD file structure. Never had trouble with my 2 year old Pro version. I also tried a standard DVD.
