Movies not playing on new laptop

[justin hess]

I've searched for this issue and find various sites saying it's a win10 issue or a general drm issue etc but can't make sense of any of it.

I have all of my movie files, legally bought and owned/downloaded in dropbox...I just bought a new laptop and am trying to play my movies and where I had zero issues playing any of them in windows media player or vlc now I'm getting nothing but various errors...they won't load at all in itunes to try that. MP4 movies from youtube play just fine but anything else...wmv files...
