my friend purchased a shw-160P6S from newegg and placed it in an external enclosure. when she tries to burn a dvd-video or data dvd in nero it stalls on 38% or 1%. the timer continues but buring doesn't seem to complete it just stops. we then tried the burner on my computer and it burns fine, nothing wrong. it just doens't seem to want to work for her's. she has an HP Pavilion a620n. we don't know what the problem is so if anyone can help that will be great. also she has a lite-on sohw-802s its dvd+r/rw if im correct installed in her computer. could this be conflicting with the burner in the enclosure? thanks in advance.
