I am trying to burn a dvd using my Sony DVD RW DRU-720A but I keep getting errors half way through burning. I have tried 2 different blank DVD and it doesn’t seem to burn well to either. I tried Memorex DVD+R and Maxwell DVD+R.
Any help on troubleshooting and fixing my problem is greatly appreciated.

During my first burns with my 1633 I had the same error message. I changed the IDE cable to a 80 wire, where my 1633 is connected as master (black connector) and the cd-rom as slave (grey connector). It’s burning fine since then. Read the whole story:
