I bought a 100 pack DVD-R 16X KODAK My burning software (Nero) says that they are illegal!!!!! What am I supposed to do???

It may be the problem of Nero or your Nero configuration files can get corrupted. If your intention is to burn the DVDs then you can try other burning software instead of Nero. For those burning softwares, I recommend you to use Astroburn Lite as this is very small in size and handy and of course, free. You can try burning with the Astroburn Lite by downloading it from here.

Hope this helps,
