I have a very important DVd that i made back in 2007...movie maker.   Unfortunately I saved it as a .mswmm file and I can no long view this DVD of my son.  I have tried numerous converter sits and downloads which do not recognize the file format.  I am using Windows 7 on my laptop currently and would like to convert this DVD so that I can view with other microsoft media viewer.  Any thoughts please advise.  Thanks, E
