Youtube download mystery??
 

Sometimes I will click on a youtube link wait until clip has downloaded then watch it, then if I like it I might decide to keep it so I open keepvid do the biz and it downloads instantly having already secreted the file somewhere on me hard disk I assume, other times when I do exactly the same thing keepvid starts downloading the file right from the begining again,can anybody think of a reason for this?
:uhoh:
