I am confused because a CD called Roxio Creator & MyDVD 9.0 DE came with my computer. I do not know what Roxio is, I am thinking it is some cd/dvd burning software. I am wondering if it is necessary to install on my computer, for example if it is the only way I can burn CDs/DVDs. I have an Inspiron 1501 that is only a couple months old. If I could get any information about this product, that would be great. Thanks.
