DVD's and Assigning controllers

Hi, Just a quick question. I recently purchased the Vfx software and controller in the UK (as a package) and wondered how I obtain the extra DVD footage and clips that are advertised? the retailer is not sure if they are sent direct from yourselves?
Also how do I assign the left hand deck on the mixvibes controller so I can put through an external mixer on one channel and the right hand deck onto a separate channel. Currently, both left and right sound outputs are combined onto one channel? I cannot see how to do this. I am sure it must be very easy, but cannot work out how.
