when using the new IFOedit 0.95 to author a DVD, I get an error message when trying to open my mpg file that says "cannot open file", anyone else have this experience or have any advice on this? This just started a few days ago...weird. I have tried using 3-4 different mpg files and get the same results. I am really excited about the new authoring feature of this free program, I just wish I could get it to work.
