OK, I ran discspeed at half the default rate. The scan was very slow but the results appear to be the same.
I installed ODC 1.70 and was able to get this to run. Here is a scan of a Verbatim DVD burned at 4x rated at 16x. The results look really good. Any idea what the one spike might be…dust?
The disc quality results on the same DVD using iHES112 drive below so to compare with the Pioneer drive using discspeed and ODC . The result appear to be the same for ODC and discspeed. The burn appears to be excellent for DVD.
Results using same BD-R with ODC 1.70 below. Appear to be the same as discspeed.
Can we assume the iHES112 drive provides accurate disc quality results for BD-R given that the DVD quality result were the same for iHES112 and Pioneer drives?
