How much set up do you want to do? The video players in VRChat will take any http url for an mp4 h264/aac video, so you can host your own videos from dropbox that way. If you don't want to mess with that and have decent upload bandwidth, bigscreen lets you stream your desktop to others pretty easily. If you don't have good upload bandwidth, bigscreen also has a new mode that does synchronized playback as long as everyone has the same file locally, a la syncplay.
