I have DVD Architect 5.0. I am trying to make a DVD with 1 film that I made, a scene selection menu and a special features menu with 2 trailers for the film. The video is all MPEG2 and the audio is W64, which are both supported file types, yet when when I go to "MAKE DVD" and render the video, it stops almost instantly and says "Warning: An error occurred while writing a file. The file is an unsupported format" This is very frustrating b/c I'm doing everything right. I've checked and rechecked the files and they're definately that right file types. HELP!
