This is somewhat off topic, but the point I'm trying to make is that I have found that cheap outsourced discs can be problematic. So, my suggestion would be to spend a few bucks more and get some namebrand discs.
A while back I bought some generic 100 CD-R at MicroCenter in Houston.
They cost $9.99 and turned out to be CMC, which others have said has improved a lot in quality. They burned fine, except every time I looked at them another scratch appeared, and any songs after 60 minutes skipped. I made some backups of some CD's for my kids and they lasted a week before they were unplayable.
