Hi, I have some educational cds which are perfectly fine but after a few minutes in my laptop, they warp and won't play until cool again. So I thought that I'd copy them to my hard drive and then back to a dvd. Their format is cdfs - is there a software package that will convert the data to the hdd and then to a dvd format. Also, what precautions should I take since I tried this sort of thing some time back and lost all the original data! Thanks in advance, Richard.
