Burn RHEL7.1 ISO from RHEL7.1

I ran the following on a RHEL7.1 system to make a RHEL7.1 bootable ISO.

[root@box iso]# ls -lh rhel-server-7.1-x86_64-dvd.iso 
-rw-rw-r--. 1 qemu qemu 3.7G Mar 17 11:09 rhel-server-7.1-x86_64-dvd.iso
[root@box iso]# 

[root@box iso]# growisofs -dvd-compat -Z /dev/cdrom=rhel-server-7.1-x86_64-dvd.iso 
Executing 'builtin_dd if=rhel-server-7.1-x86_64-dvd.iso of=/dev/cdrom obs=32k seek=0'
/dev/cdrom: "Current Write Speed" is 8.2x1352KBps.

I think growisofs has a slightly confusing name and an odd syntax.
