Renamed avi file keeps showing old name

I am running Windows Vista Ultimate 64-Bit. I have some avi files with messy names, so I renamed them to something more manageable. No problem, when I play them in windows media player it shows the new name in the list pane (on the right). The problem happens when I move the files (before renaming) to a shared folder for streaming to my ps3/xbox 360. Once they have been put in that folder it's like there is some sort of memory on the original file name. I can rename the file to whatever I want, and that name stays, but then when I play it in windows media player or on the ps3/xbox 360 it shows the original (messy) file name. The only solution I have been able to find is to rename the files first, and then drop them into my shared folder. Once they are in the shared folder it is the point of no return and the name they have is the name they keep. I have tried "abcAVI Tag Editor" and that is showing the file name as the title name. So the original file name doesn't appear to be trapped in the tag. I tried moving the files out of the shared folder then renaming.. it worked until I put them back in the shared folder, then it's back to the original name. Do I just need to refresh the shared folder somehow? Any help would be great. Please and thank you.

Right-click on the folder that has the files you're sharing and select properties
Click on the sharing tab and click on Advanced Sharing
Click on the Permissions tab and make your selections there

I tried tinkering with some of those options, it doesn't seem to have any affect on the problem I am having though. I can share the files fine, its just showing the old file name on wmp/ps3/xbox360 instead of the new one.

For any future readers of this post who may have the same problem, I found a solution. All I had to do was change the file names within the Windows Media Player library. Problem Solved.
