ok, let's go back to the original issue, because the [FILE] token should work just fine. When uploading a file to the server, a Guid (unique id) is injected into the filename between the filename and the extension. Then when the file info is retrieved, the Guid is stripped out of the filename. So, without any changes at all, the NiftyVideo should have worked just fine.
Now, when uploaded, the file written to the server should have a full Guid as part of the filename, example:

Notice, that this does not look anything like the filename that you mentioned in your first post. I'm not sure if you copied/pasted the exact filename from your server? or if you where just making a point by typing in some garbage characters.
Can you upload a file, then let me know 'exactly' what the filename is that you uploaded, what the filename is that is written to your server, and what the filename is in the HTML source when you view source on the portal when viewing the repository module?
