    Windows 7 here we go again with File Copying issues

    trying to copy a wmv file from a cd rom to my hard drive in windows 7 and seeing that stupid "calculating:mad:" message that goes for 200 years with no actual copying being done. What is this and how do i fix it? I used to see this crap in vista too.
