Macbook A1181 Combo Drive Upgrade?

[eob2000]

I have a MacBook (A1181) (Mid 2007) with a CD-RW Combo drive, I was wondering if it is possible to upgrade the drive to one capable of DVD-R or DVD-RW write support. Can it be done? If so what drive would I need to buy

Apple won't sell you one?

Optical drives are pretty generic, the only difference is, there are two thicknesses (Google), buy the one that fit and DIY if that's what ur thinking.
