Thanks, I think this would be a great addition for users with robots.
A couple of ideas for how the option could be presented:
GROUP I/O Error Handling
CHECKBOX Don't show I/O error dialogs when burning multiple copies (but log error and reject failed discs).
COMBO Number of successive failed discs before queue is stopped: 1,2,3,4,5,No limit
We'd be happy with just the checkbox, but I think it would be neat to have the option to specify the max failed discs as well. This would handle the potential case where a drive stopped working properly.
