I have been using dvdfab platinum to backup my childs dvd. I use a plextor 708uf dvd burner and all the backups work fine in my home dvds but will not play in my minivans dvd. I have used both + and - dvd r. Does anyone have an idea what I can do to have the dvd backups read in my minivan. It keeps ejecting the dvds saying bad disk. Thanks for your input.
