Hi, I'm totally new to this process so please forgive my ignorance. I just bought a burner and two dics came with it 1. Sonic MyDVD and 2. PowerDVD. I plan on making back up copies of the DVD I currently own. According to another thread in the DVD-R for Newbies section, it was mentioned that there are 2 programs needed for copying; Nero and DVD Shrink. My question is do I need to install the discs that came with the drive or will the aforementioned software suffice? Thanks.
