Why are the videos I upload to my Dropbox account playing sound but no picture?

[dollyonline]

I have never had this problem before and it is very frustrating. I have a ton of concert videos that I took on my Iphone. They upload to dropbox. From there I copy them to my PC and create folders to save them. I have done this for years. But now when I do it all I get is a music note and sound. The videos are not there. I have not changed anything. Why is this happening??? Please help

as per advice of a friend I downloaded VLC media player for free and made it my default media player and it now works.... Good luck I hope your childrens videos are safe.
