Okay, I posted once about this in another thread, but since then I have gotten a warranty replacement with the exact same problem so perhaps this is a configuration issue.
The symptoms: The drive recognizes pressed DVDs and CDs without a hitch. It reads all the DVD+R I have thrown at it, albeit with some pretty disgusting looking KProbe scans. However, perfectly readable DVD-R burned by the SOHW-1213S or my DVR-108 are not recognized at all. The burner tries to read the disc and after a while it just gives up. KProbe and all other utilities report “No Disc.” KProbe scans of pressed discs look pretty good.
I’ve already returned one drive and gotten a warranty replacement, but the new drive has the exact same behavior.
I have the drive set as Master on the primary IDE controller all by itself. I’m using an 80 pin cable too. The PC is self-built, using an Asus P4PE (i845PE) motherboard. I have installed Intel’s INF chipset drivers, but have not installed Intel Application Accelerator. I’ve tried both with and without Application Accelerator before, so that’s not the issue.

Several people on the Lite-On website’s discussion boards also report the exact same problem, but they’ve never gotten a reply from Lite-On.
