Hi there,
my friend taught me a little about cd-rs, you have to make sure what cd manufacturer made the cdr you bought.
read this article
here to know more about it
there are links to threads about which cd manufacturer is good at the bottom of the article
i personally trust prodisc only (but that doesnt mean that all cdrs made by them is good. I used to have some very cheap prodisc cdrs but because the dye is too thin or somethin, it came off after 1 month!!! i guess its you get what you paid for!!!)
hope it helps
--edit--
a quick way to find out your cdr manufacturer is
put the blank cdr in
run your nero burning rom
click view
click recorder
click media info, media info window pops out
hold shift key and click refresh, the manufacturer name should pop out
