Windows 8 Consumer Preview 32-bit not installing with Disk Utility

I have a late-2011 13" MacBook Pro (Mac OS X 10.7.4). I downloaded the Windows 8 32-bit Consumer Preview ISO from the Microsoft official website (so there is nothing illegal there) and I am trying to burn it to a Maxell 4.7GB (up to 16x) DVD-R using Disk Utility. I moved the ISO to the left menu and I selected it. When I press Burn, Disk Utility pops up an error message and says "'Unable to burn Windows8-Consumer-Preview-32bit-English.iso.' (not recognized)" Am I doing something wrong?

Also, it would also be cool if someone could tell me how to install Windows 8 Consumer Preview 32-bit (English) the easiest way. You really don't have to do this but is this guide (http://reviewnotepad.wordpress.com/2012/02/05/how-to-install-windows-8-on-a-mac- with-bootcamp/ and http://www.youtube.com/watch?v=yYiR-4jqMuM&feature=related) and video accurate?

Thanks for all the help in advance!!
