What program are you using to burn discs? Have you tried Windows 7's built-in burner?

ImgBurn is a great free program: The Official ImgBurn Website

You could also download the latest firmware update for the Matshita drive: UJ890AS MATSHITA

I've also noticed you are using Windows 7 Basic, which probably explains why you can't burn to disc.

Download ImgBurn and you'll be fine with that, and don't forget that USB flash drives are coming down in price so using them could be an alternative to CD/DVD storage.

In that case, we have to consider that DVD-RAM drive has a problem or that you need to be using DVD-RAM discs.

Do you have access to another computer that has a DVD-RRW drive and try that? It would eliminate the blank discs from the equation.

From what I can make out, some computer manufacturers sell computers supplied with a DVD-RAM drive, but don't have DVD-RAM support meaning you'd need to update the drive's firmware.

It might be easier to bite the bullet and replace your DVD-RAM drive with a DVD rewriter drive.
