Hi,
I am a long-time user and have never had any grief from ImgBurn but with the last three disks (brand new TDK DVD-R) they have all exited early in the verify-process with Unrecovered Read Error as can be seen in the partial log-file output here (starting with the Export Successfully Completed! msg after the write) from one of the sessions:

I spoiled three disks before turning to the forum as I figured there might be something wrong with the medium but...also, I can play play other DVD's OK so the drive seems fine.
So, what gives here?
