I recently got Nero 8 Ultra. While trying to use Nero Vision to make a new disc, when I press "Finalize Disc", it says "Media not supported." I don't really know what it means by "media", but I hope it's not the discs, because I just bought them.
I'm using Sony DVD-R discs, and my disc drive/burner is a "HL-DT-ST DVD+RW GSA-H31N", in a Dell XPS 410 tower with Windows XP SP2.
Thank you.
