right... when stamping discs they always seem to have an over run... to =
which I'd simply say, my deal is X pieces. your computer controlled =
machine makes exactly what you tell them to. I'll take delivery of X and =
pay for that and you have to destroy the over run. thats your mistake =
and your problem.

as for getting your image there, I'd recommend creating an ISO disc =
image on a USB drive and sending that. DVD-R media tends to have errors =
even if it has 100% confirmation
