I need really help.

I've ripped the game sega extreme sports(PAL) with 38 tracks. Then ive unzipped them(with winrar). What should i do now?
Until now, ive burned only the raw tracks but when i want to burn the iso data too, discjuggler says " unkonown". What can i do? Should i use another burnsoftware?
Can someone help,please?
sorry if my for my englisch is terrible, i'm from germany.
