May end up buying another copy

I tried to get my Win98SE box to do something with that bad disk, but
the drives and the software I was using kept locking up when it
encountered those parts of the DVD. So unless there's a DVD burner that
can handle disks like that really well, and I ran into one drive that
seemed capable but I don't have access to it right now, I might as well
re-buy that disk in a single pack release...

Update: I did go back to re-buy TM GXP 18-20 and this time the copy
was just fine. I've decided to snail mail the defective disk to Fu-nimation
so they can get an idea of what got through their Quality Assurance
checkers. If they reciprocate in any way, which I don't expect, it'd make
my day.
