well you should have no problem playing this file with windows millenium. i have an old laptop with windows 98 on it and it plays mpeg2 files fine. make sure its the file that is 256mb in size. just right click on the file, select properties and you will see what size it is. if it is only about 90mb then you are trying to play one of the rar files . it has to be the mpg file that has been unpacked from the rar files.
