I am having trouble with the Nero CD-DVD Speed app (v. 4.01).
If I run the “Disc Quality” test using my Lite-On SOHC-5236K Combo drive, it works fine, and will check DVD+R discs.
But if I try the same thing with my new PX-716A, I get “Error initializing test” every time. Other tests work (like Benchmark and ScanDisc), but not this one. I tried rebooting; I tried upgrading CD-DVD Speed from 4.00 to 4.01, but no change.
Related question: What’s a reasonable Quality Score in this test? Lite-On routinely reports stuff between 84 (for an overburned Fujifilm DVD+R I made earlier today with my PX-716) to 93 (for a standard DVD+R I burned with my old PX-708). The manual included with CD-DVD Speed is a bit out of date, and doesn’t even mention its DVD-related functionality.
