This is guide, made by myself, which describes how you can put a video into your RP´s
1.Copy the underlined URL from the video you have.
I underlined the URL with red!!
It´s the second one not the URL above!!!
(ignore the watermark)
2.In the RP section click on the little video button. A new window opens where you can copy the URL. Do it and click Ok.
The only important thing is that you copy the second URL, the one I underlined, If you take the other, it just copies the URL without doing something.
That´s it!!
(I hope it helps even it´s not very good)
