Dave, I have just installed a new DVD burner in my computer (a Pioneer DVD-RW DVR-105 internal drive) and am trying to figure out what kind of blank disks I should be using. There are apparently five different blank DVD formats. Do I want DVD-R? DVD-RW? or ?? Also, if I just want to burn lots of data onto a DVD disk, can I use my Roxio Toast Titanium to do so, or do I need to use a special DVD-friendly app like iDVD?
