You’ve heard warnings of bad DVD media, most likely. But how can you tell whether your stack of DVDs is a dud or good? Evidently, you can’t tell by a brand- you have to do some sleuthing to see if it’s good or not.
Sadly, this method only works after you have bought that stack, but at least you can tell whether to get the same kind again.
First, you’ll need to insert your blank media into your Mac (this method only works on Macs, and I can only say that it works on Leopard).
