Definitely sounds like a problem. I can think of a couple of things you can try
The first that comes to mind is the posibility of a corrupt download or a bad burn. In this case, I'd suggest checking the mdsum of the ISO and make sure you burned the ISO correctly. Try burning at a slower speed too.
I also noticed you downloaded a beta release. Try the final product, which has been more extensively tested.. Here is the URL

You should be using some feature labeled "Burn cd image" from your burning software.
