roxio says something like "disc created but an error has occured" while Nero states:
Foreign Image File:
The entered block size does not correspond to the image length.
The block size may be wrong. Do you want to correct the value or ignore the problem?
and if you click Correct, you get:
Type of image - Data Mode 1
not checked - raw data
block size (bytes) - 2048
image header size - 0
image trailer size - 0
It's also the right size now :) 884 MB (927,580,160 bytes)
I used Daemon tools to mount a virtual CD and then used the Asus Boot tool to create a bootable USB with your image content on it.
