A very great part of the problem is probably the length of time that it takes either of those CDs to boot. I have had to hold the C button down for almost 4 minutes at times to boot different Macs with those programs. It wears my patience to startup from either program. On the same hand, it also takes me a while to boot to Drive Genius, so it looks to me like six of one and half a dozen of the other when it comes to booting from a disc that is other than an Apple original installer. Perhaps trying again to boot to your utility CD with a little more patience might be successful? It's worth a try at least.
