Query: Getting about 30-40% Success in burning with these, unacceptable.

Never again am I buying Memorex anything. First of all the spindle was broken due to crappy packaging, which is Amazon's fault. But the fact that less than half of these discs can be burned is appalling. I bought these hoping to save some money, but wound up causing myself an additional 6 hours of work, burning and reburning hoping I'd get lucky and hit one that would finalize. Never buying Memorex again, it won't save me or my clients any money to gamble on cheap media.
