Hmmm... never seen that yet. I click Upload Videos. (Pic 1 "Screen3").
I see this (Pic2 "Screen1") get a series of clicks and then I get a list of all the stuff that has already been uploaded by others. (Pic 3 "Screen2")
Now at the bottom that last screen there is another "Upload Videos From Your Computer", and all that does is add another screen like the one in Pic2, and adds it above Pic3 in the page.
I thought I was on the right track this weekend, but there is obviously something stopping me from going further. Well... guess I'll just have to be satisfied with the ugly YouTube stuff for now.
Thanks Toomse. You rock!
