I have yet to make a successful back up of some data files useing Khypermedia DVD burner with Nero 6.3. Sometime the red light will show its burning the dvd, then after a 1 minute or as long as 15 minutes it will stop and say session failed. Funny thing is when i take out the dvd there no sign of any data being recorded on it. H E L P I tried alot of different modes in Nero.
