[CentOS] Using cdrecord on CentOS

Hi,

I'd like to use cdrecord on the command line. I'm currently reading the 
relevant chapter in Carla Schroder's "Linux Cookbook". Unfortunately, 
some of the tricks and hints included in the book don't seem to work the 
same way on a standard CentOS 5 install.

1) Am I supposed to be root to use cdrecord and burn an .iso file?

2) How do I specify a device? 'cdrecord -scanbus' doesn't seem to work. 
Say my CD burner is /dev/hdc, would 'cdrecord dev=/dev/hdc' be the 
correct way to address it?

Cheers,

Niki
