Ridisc (RITEK G04) & Toshiba SD4900 player compatability?

Has anyone tried these two together. I plan on buying a burner and media together, and I don’t want to get stuck with 50 dvd-r’s that don’t work in my player! Also, is it worth buying the NEC ND-2510a over the ND-2500 for future DL burning? Thanks a lot!
