I'm having the following warning whenever I try to burn CDs as a normal user with app-cdr/cdrtools-2.0 but not as root, and the user is a member of the group cdrw. The CD burns fine but it looks like theres still a problem somewhere with the permissions.
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.
Those messages are relatively harmless. All they mean is that the burning program is unable to guarantee itself as much CPU time as it could possibly want. You can guarantee it that time by not running CPU-intensive programs while burning CDs - modern CPUs are way fast enough (I've done many flawless 8x writes using a 68040) for that to be easy.
You can avoid the problem by using sudo or making the burning program setuid. Sudo is largely preferable in general because you can set relatively fine-grained permissions, but if you're the only user of the box you might prefer the convenience of setuid.
