Query: The New Batch is a Disaster...

Like the poster below, I purchased 2 packs of 100 Memorex -Rs from Amazon over the winter and the discs were flawless. Unfortunately the new batch I purchased at the end of April (and which I assume they're still selling now) don't work whatsoever, despite having the same manufacturer. They won't burn at high speeds -- in fact on my PC drive they won't burn AT ALL. Unfortunately this great bargain seems to be a thing of the past. I'd avoid them at all costs for the time being.
