Yes, scanning capabilities would be greatly appreciated. I will always choose a BenQ as my first drive (if I could only have one) because of this feature, as I MUST be able to evaluate the quality of my burns in some quantitative way. LG's may be very reliable and generally have excellent burn quality, but they do choke quite badly on some lesser quality media and I really cannot evaluate this behaviour without my trusty BenQ's. Without this feature, LG really does not have a hope of becoming the enthusiast choice regardless of how well they tune their firmware. I may sell them to my clients as reliable backup devices, but I will not trust them as my single choice for my first burner to decide what I will implement for people.
Despite your complaints about their CD error correction issues, kudos to LG on their excellent DVD error correction. I just recently got a messed up original DVD disc which I have been trying to rip and reburn so I can watch it smoothly in my DVD player. Most drives had severe problems reading the disc to any degree (tried on six recent Pioneer, Samsung and BenQ current models) if at all, whereas the LG's (4163B and 4167B) scanned through most of the disc up until near the very end where it finally failed. Head and shoulders above my other drives, I was very surprised--it was a stunning difference.
