Actualy, we've seen many problems where a cd will boot fine on one CD and not on another and it's still a problem with the CD (too fast of a burn, some drives deal with high speed burns better than other I guess). But if you burnt the ISO at 4x then I don't expect that is your problem. I don't know what it is though if it's not media related. Have you tried booting with Smart Boot Manager???
