That's the same information you can put in if you find the file in explorer and go to it's properties (alt-enter), right? If, like me, you can't enter in the information for an .avi file, I believe that renaming it to .mpg, entering the info, and renaming it back to .avi might fix your problem. At least, I know that it does keep the information with the file when you enter it like that, but I don't know if it suits your needs. Hope that helps in some way.
