You shouldn't draw a conclusion based on that alone.
Refer to NewEgg's DVD Burner section
65 burners listed. Of which, the following indicates the number of their drive sold as "This item is warranted through product manufacturer only":
1/1: Pacific Digital
So, if that warning / message were to mean something, then it would imply to avoid the following drives: ASUS, BenQ, LG, Memorex, Pacific Digital, Pioneer, Plextor, Shuttle, Toshiba ... and some of the Samsung and Sony models. A bit ridiculous if that were the case.
Thus ... you can't judge a drive on that alone. Just my humble $.02.
