Go for the custom install.
If not - with Quicktime you will likely end up with two versions on your computer.
Let us hear about that New A510 camera.
I have not heard any first hand information on the A510.
I just bought the new canon A 510.The software cd that comes with it contains two items that are already on my PC.Quicktime is one and the other is
Photo Record 2.2 which came with my canon printer.
My question is should I install the whole CD or try custom install and skip those two items?
