I don't have it, but I think it should, e.g.:

Can't really think of anything else. My advice would be verifying the disc against the image. If Nero can't make it alone, you could try burning again, enabling verify (dunno but I guess the option will be available). BTW Verify is not the same as test write, verifying is comparing with the source _after_ the writing is done completely.
Otherwise if you feel like installing stuff, this is a very powerful, free, no-nonsense burner:
