 |

I would ask what that's meen:
| Code: |
Blocks total: 359849 Blocks current: 359849 Blocks remaining: 274
cdrecord: Operation not permitted. WARNING: Cannot set RR-scheduler
cdrecord: Permission denied. WARNING: Cannot set priority using setpriority().
cdrecord: WARNING: This causes a high risk for buffer underruns. |
Pozdrawiam

since CD-burning is time-sensitive, cdrecord asks the kernel to give him top-priority. So he can make sure no buffer-underrun occures.
However, the kernel denies that request because cdrecord (=YOU) doesn't have enough privileges to do so.
Are you running cdrecord as root? or as a normal user? is is suid-root? |

You could do that. setting an executable suid-root is essentialy the same as running it as root.
With me, I don't have the suid-bit set, and can burn fine, but YMMV |
