Turning your CD burner to a DVD burner

Anyone know of a way to make your CD burner a DVD burner?

I think there’s only one way - buy a new device.
Seriously, the optics withing the burner are different for CD and DVD, and the CD burner optics cannot burn DVD, just as a plain CD-ROM device cannot read DVD discs.

It ain’t possible.

You’ve to buy a new drive, but they’re cheap (€55) nowadays so that wouldn’t be a problem.
