Glad to hear it (sort of) works for you!
I presume you are running W2K SP3; there is conflicting info in Ahead's documentation whether SP2 is enough.
Did you check if file dates are preserved upon copying? In my latest experiment, when I used Explorer to copy several directories from my HDD to an MRW (Mt. Rainier) disc, about half of the copied files got the current date and time. (This is for XP SP1, and I've not checked non-MRW discs so far.)
Do you have any estimates for the writing speed on your burners and media? For instance, typical reviews list timings with InCD 3.x for copying about 400MB of data.
