Can't burn CDs with newest iTunes - Averatec laptop

I've seen this problem posted several times. I've tried various fixes -- repairing/reinstalling iTunes, setting my burn speed at a slower rate, checking with my manufactuer for driver updates (when I spoke to an Averatec rep they said that the necessary driver updates would come from Microsoft and I've updated all I could there). Also, I can burn CDs fine through Windows Media Player so I'm thinking it's an iTunes issue.
Any help will be greatly appreciated! Below is my most recent diagnostic results.

If you have multiple drives on the same IDE or SCSI bus, these drives may interfere with each other.
Some computers need an update to the ATA or IDE bus driver, or Intel chipset. If iTunes has problems recognizing CDs or hanging or crashing while importing or burning CDs, check the support site for the manufacturer of your computer or motherboard.
