I have to say my LiteOn 165p6s is a good burner and a great scanner with KProbe2, but it does have a problem with burning disks with higher jitter than my BenQ 1640. I actually recommend BenQ b/c of it’s Solidburn being more mature than the LiteOn 165p6s, as the Solidburn really works well, while my LiteOn 165p6s under different test firmwares (currently testing MV94) I see still needs a lot of improvement on the jitter side. It’s most pronounced problem is going “back and forth” on jitter, with generally always a “jitter hump” at the start of the burn, whether burning at 8x or 12x, and regardless of media (MCC003, MCC004, tyg02) I use. It’s obviously a quirk that needs further ironing out, but while the LiteOn engineers are currently busy on a new LiteOn model, they don’t have time to tweak the test firmware and get the jitter much lower (for example, a tyg02 burned on a 1640 will avg. 7.8-8.5% jitter, but on a 165p6s will avg. 9.6-9.9%, so that’s a significant difference).
The LiteOn 165p6s is a good burner, and it will smoke a BenQ at 8x and 12x, as the LiteOn is the more aggressive burner. As for which test firmware, I’m leaning most towards MV94, as the only other two that seemed consistent in results were MV7U and MV8P. However, the only one of all those with no documented problems or doubts was MV94 that I’ve been able to see. At the same time, there is no jitter data from most f/ws except the most recent ones, so it is hard to tell which one (except MV9N, which is not consistent on burns nor jitter) might be best to use. That said, my BenQ 1640 does consistently adjust and improve burns and jitter, so in comparison is slower to the 165p6s (for example, it might burn a 4.36 gb tyg02 at 8’ 45" whereas the 165p6s will burn it at 8’ 22" at 8x), so the 1640 is slower by at least 20 seconds to the LiteOn, but the jitter is much steadier and most definitely lower than the 165p6s results. Of course, if the LiteOn engineers can fix the jitter “back and forth” and get the Hypertuning and Online Hypertuning truly fixed, then the clear edge would go to the LiteOn 165p6s.
