Starting with version 18.104.22.168 I get the following error message every time I use DL - Verbatim MKM-001:
"Media inserted in Drive E: is single layer
Please insert a double layer media to start the write process"
If I cancel the error message, I can get the program to operate with no problem. I can use either VSO engine or ImgBurn. This problem has never appeared for me using any other version 4.xx. Typically, when I use DL, I am using Clone mode. So exact procedure - start DVDFab, place original in drive D: and let PathPlayer analyze. Place blank Verbatim DL in drive E: and set my target to the drive rather than a directory (my default). As soon as the target is identified, the error pops up.
I have no problem recognizing these disks as dual layer using DVDInfo Pro. No other decrypting programs that I use deliver this type of error.
As a last note, I occasionally get another error stating that the "DVD on E: is a data disk. You can choose Clone to copy it". This is spurious as well since I can cancel this message and proceed. Again, only noticed with the latest version.
