Ok, so I think the mystery is solved. I first called Pioneer USA directly, and the guy confirmed that the DVR-110 (not the DVR-110D which is readily available in the US) was not sold in the US, but he didn’t know why. Then after some hunting around on other forums, I finally figured it out: ASUS re-brands the Pioneer DVR-110 as the ASUS DRW-1608P2S (and also re-brands the Pioneer DVR-110D as the ASUS DRW-1608P2). So it appears that Pioneer doesn’t market it directly in the US, letting ASUS do that. It’s the same drive, as it can be flashed with the exact same Pioneer firmware updates, and it explicitly advertises the DVD-RAM 5X write capability. I found it at NewEgg.com as low as $42 US. However, I’m now comparing the Pioneer with the LG 4167B, which is very similar in nearly every way in terms of features, performance and price. My goal is purely DVD data backup, and comparing the reviews here on CDfreaks, and also on other sites, everyone consistently says that the LG 4167B is slightly better than the Pioneer from a writing compatibility standpoint (and seemed about the same good quailty on writing). And both drives seem to work fine on Macs, which is what I have. I had initially leaned toward the Pioneer since most Macs ship with Pioneer, but Mac OS X 10.3.9 doesn’t natively support this particular Pioneer. Both work fine with patchburn, so no real advantage for Pioneer vs. LG. Anybody have a strong opinion either way between the “Pioneer DVR-110/ASUS DRW-1608P2S” and the “LG 4167B”, when the goal is purely DVD backup (ie. don’t care about read speeds nor DL, etc.)?
