It's really a simple file copy process but it's hard to explain. It really doesn't matter what the reason for doing it is, either. The point is, I absolutely know without a doubt that doing this will fix my problem because I've tried a few movies and it does fix the problem.
I have lots of folder.jpg's **denotes variable
Video/DVD Movies/*Movie Title*/VIDEO_TS/folder.jpg
All of those need to be copied to
Video/DVD Movies/*Movie Title*/folder.jpg
Notice the folder.jpg is originally inside the VIDEO_TS folder. I need it to be copied one folder up, beside the VIDEO_TS folder. Then, two identical folder.jpg files will exist for every movie. Media Center automatically picks up the one under the VIDEO_TS folder and my Xbox Media Center automatically picks up the one next to the VIDEO_TS folder. When I browse movies, it only looks one folder below the *Movie Title* for a jpg file so it has to be next to the VIDEO_TS folder. XBMC doesn't bother looking inside the subfolder VIDEO_TS as well. If I select the movie, the VIDEO_TS folder does have the correct thumbnail but I want the thumbnails to appear on all the Movie folders so it's easy to scroll through them all.
I hope this makes more sense. I've already started manually copying but it would be good to know of a good program to do something like this. It could almost be done with the cmd prompt in Windows but variables are the key. It has to copy files (which is easy) but the filenames have to cycle through all available folders to complete the process.
