Configuring the Buffer for a DVDRW

Hello, I am using SuSE 9.0 and I have installed a DVDRW Dual Format in my box. When I use the burning software, it does not recognize the buffer for the RW. It's using a generic driver, and I would like to know if someone could tell me how to configure the driver to recognizer a 2 mb buffer. Sincerely, Robert Pitt
