Setting up a blog

I have viewed several blog accounts and finally settled on Blogger.  I have spent the last couple of hours setting up the layout and deciding how I want the overall page to look.  I have viewed and played with many gadgets.  The one gadget that I would like to use is the "video bar".  I have been able to link one video to the reel but when I try to link another I have no success.  Any help or support would be appreciated.
