Do nLite'ing as normal, then make an ISO image, then before hitting next, change the Mode to Direct Burn, and hit the button to start the process to burn. It goes through the MB's really fast, then says write successful, but never even messes with the CD drive. If you check the Verify checkbox, it says verification failed. If you change it to burn image, however, it will ask which image to burn, and then properly burns it.
This is in v1.4.1, but maybe also in 1.4.5 beta
