Thanks as always for the input. My flashed 8601's had no problem with regards to software on my computer so, based on that, I think the issue lies within the new Benqs. It just seems odd that the new Benqs don't like Ritek 16x+ media when the flashed Phillips/Benq (I was running B7P9 f/w on them) made and continue to make flawless burns @16x on that media. The scans of those discs were above average, not great, but the discs themselves played wonderfully on my Pioneer dvd player.
I'll try flashing the new Pros to B7P9 and see what I can see. If they continue to be unable to burn successfully @16x or they burn too slowly, then I'll just return them to TigerDirect and get my money back.
QUESTIONS: I realize this question is off-topic, but what burner do you like besides Benq. People seem to really like their NEC 3500's. What's your opinion? I see you have a NEC, what is "LIggy and Dees v.2B6 f/w", is it different from factory f/w? Finally, is the 3500 the fanciest NEC or is there something beyond that? Thanks again.
