Help - SONY DVD RW DW-Q28A linux drivers

[Coastie]

Tried to burn and read CD but Xfburn says the drive is empty with CD in it. DVD burn/read works. Called shop where I bought burner. Told a driver(s) problem. Told to check in config files to see if there is a line with a question mark. Don't know how to find. Also told just do a Google search for the drivers and download and install. Did but was unsure which site would be save to use and Firefox wanted to open with CD burner.

Help!
