Hi there
I hve also had this problem. Why do you want to go through the hassle the easiest way is for them to upload it onto you tube and then they should just supply you with the info of where they have uploaded the videos. you can then go onto the you tube site and you will see the code next to the video. You have to copy this code and then create your own page in BV . Then click on the "html" block in Bv it will now drop that block onto your page. Right click on it and click on properties then paste the code from you tube into it.You might have to move your Html block around untill it displays in the right spot.
Have a look at
