So they did away with the direct link.
I get it. Must have been on drugs.
So from my public folders the link plays the movie immediately without any Dropbox text.
It just opens and plays.
The other folders, using the share link, will show the dropbox logo and a download link.
And it will play by hitting the play button. But it does not fill the page and keeps the dropbox text at the top of the web page along with a download link.
Is that the main difference?
Tested using a browser that does not know my dropbox account info.
