unpacking moviedat.dat files ??

[chief995]

I was looking at NCAA Football 2003 NTSC, and there are no pss Movie files. There is a file named "Moviedat.dat" ,is there anyway to unpack this file to edit it possibly? If so, with what?
I did try & open it with an unpacking tool used with Nascar 3.
That wouldn't work though.

Thanks
