quick Nero question...

[Cheese78CA]

Why isn't the "Allow more than 255 characters in path" option in "Relax ISO Restrictions" relected while burning? Even though I checked the box, I still get "The following Joliet files or folders had to be renamed to make them compatible with the CD file system:" error and those files are truncated in the burned CD. I've looked online everywhere and there is no elaboration on why it shouldn't work. Any help would be greatly appreciated!
