I've been using a new Pioneer A07 DVD burner with DVDA1 with no issues.

When I try to burn from DVDA2 the process begins but stops every time and I receive the following error message:
------------------------------------------------
The command failed due to a IOCTL error. Your interface orr drive may be configured incorrectly.
------------------------------------------------

Pressing the details button reveals this:

------------------------------------------------

Thanks in advance for any suggestions.
