how do I change a movie title or delete a video?
 

for some reason, it wont allow me to change a movie title, and the title was uploaded incorrectly...

so I want to either change the title, or delete the video and reupload it with a new title... however, I see no what to delete the video, at the button of video options there is a spot for "delete reason" where it asks for an explanation but no way to actually delete the video...

how?
