I ordered a 50 pack of HP+R DVD to back-up my collection. I am using DVD Decrypter for the whole process but when I burn one, I get to about 10%-20% and I get a I/O failure error(foolish of me I forgot to write down the exact message). My Magic I/O 8X DVD burner locks up and will not open until I restart Windows XP. I have had 1 successful burn with the 1 blank DVD that came with the DVD burner but since I got these HP dvd's I have had 4 failures and gave up. I burned at 2.4X (twice), 2.0X, 1.0X then gave up just in case I could return them. I am smarter now, I going to order Riteks but before I do, am I doing something wrong with the HPs?
