Tiger burn problems


dualie G5. X.4.3
I'm using "iBurn" as I did with my G3 that ran X.3.8

I'd drag n drop folders or items from folders, then click burn and all was well.
There was a point during each burn when I'd be asked to authorize the burn, as some of the stuff was from the User/Lib.

I've tried this same approach a couple times with the new lad and it quits halfway thru with this error.

the operation cannot be completed because one or more of the required items cannot be found. (-43)
Could not open data fork of "<unable to get file path>". (-43)

One of the folders is sourced from "User/Library"

so I just tried only the docs folder. Same thing.

any ideas?
