I burn a lot of CDs and here's what I've found:
Sony (NO problems)
Memorex (tons of duds, avoid like the plague, the last batch was 60% bad)
Memorex Black (a few bad ones in the stack, say 5%)
Maxell (usually a few bad ones in the stack, say 8%)
Philips (occasionally a few bad ones in the stack, say 3%)
When I say bad I mean that they either wouldn't record at all, record all the way through or finalize properly.
Anyone else care to add to the list?
