Hi, I have an external dvd burner i just purchased and i use it on my hp pavillion ze 4800 laptop. The problem i encounter after shrinking the dvd into the to audio and video folders is when burning with nero. It starts to burn but stops either at 1% or 3%. At first the burner makes the louder noise like it is going to write but then it just kind of idles. The remaining time still counts down but nothing happens. SOmeone please help.
