I'm trying to backup some movies to my new 300GB HD. Then, if I want to watch them, I could burn them to DVD-RW and watch them on my DVD player. I have a Lite-On SOHW-812S. I successfully burned a movie to an Imation 1.1 DVD-RW (4.7GB) using DVD-Shrink. I was able to watch the movie on my DVD player. Then I tried to erase it so I could put a new movie on it. However, this is where I ran into problems. I was new to using DVD-RW's and selected "Erase this DVD-RW" from the My Computer option in XP. It said "DVD erasing wizard did not complete successfully." Now my PC won't recognize the disc. I tried burning another movie with it, but it says "please insert a DVD." I tried erasing it via Nero (5.5) and it doesn't recognize that a disc is even there. When I place the disc in either of my DVD-ROMs it won't recognize the disc. When I try playing it in my DVD player, nothing happens.
What did I do wrong? What can I do to make this work in the future? What DVD-RW (or DVD+RW) media would you suggest?
