I'm assuming that Windows Media Player is unable to play the file due to some issue with the program so I would recommend finding another DVD player. A free alternative that supports many different file formats including the ability to play DVDs is 'VLC Player'. It's totally free and can be downloaded from the link below.
Make sure to download the Windows version. Hope that helps :D.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
