I have Movie Studio 14 pro. I have read on the community that you are aware of the problems associate with ac3 opening along with the mpg file. Mine doesn't come in with the mpg file. Have you solved this yet.. I have also had problems with the pre-render as it doesn't save the file to the folder I specify, then when I do find the file it will not open it. Please let me know as soon as possible.

Best,

Brendan
