I've been given a bunch of files by a client to edit. They were uploaded onto GooGle Drive and then downloaded to my external drive. When I go to import them into Vegas via Project Media, I get "None of the files dropped on Vegas Pro could be opened". Most are .AVI files. Some are VOB ripped from a DVD. There were also some photos which imported fine. It's only the videos. And I can vierw them on my PC outside of Vegas.
