I am new to Mac, just recieved the iMacG5, and I am trying to acclimate myself to it. I was looking for software to make backup copies of DVD's. Popcorn was touted, but when I went to their site, they excluded anyone from logging in to their discussion groups. Based on the nature and number of complaints I could well understand why. Their software is only downloadable, which means to me they are not sufficiently confident in its current performance to invest in carving it into the hills and valleys of a CD or DVD, and need to continue to revise the program as they go along. Does any one have experience with another program that is reliable?
