Used Roxio 9 to copy a DVD, both DVD+R and DVD+RW, and then write it to a Sony DVD+R disc. Then attempted to finalize the disc and get the message "Insert an appendable data disc that is CD media or DVD write-once media". If a DVD+RW disc it used the disc plays without issue, not finalized. However, the DVD+R discs all give this message when finalize is attempted. Runnig windows Vista on a brand new Dell laptop. Standard DVD devices replies with no disc found. Creates a finalize error also when I attempted to use a standalone Sony VRD-VC20 device to finalize. Any idea on what I am doing wrong?
