Buffer I/O error on device sr0, logical block

This error is telling you that you are unable to read the CD drive.

This doesn't necessarily mean that the disk has not been burned correctly. 

It could be a problem with the IDE...try the following:

• Put in the CD
• When you get to the menu press F6 (I think, don't have it in front of me)
• Add the following (without the quotes) to the end of the parameter list that appears at the bottom of the screen, "irqpoll all_generic_ide=1".
• Now try run it from the CD. You'll need to do this for the install and the live view.

Check this works off the CD before installing.
