Do you have the main concept plugin installed?

Also, where are the logs? I assume you've read viewtopic.php?f=40&t=220400

Version is 1.6.1.
Removed it temporaraly and coding with NVidia is working again.
Have already sent a support ticket to MainConcept.

Actually I do not really need MC Plugin beside the DVD-vob creation, since DR has no built-in solution.

This is what MainConcept Customer Care stated:

"We are aware of this incompatibility and have internal report MCBMD-88."

Hope this issue can be resolved for good.
