InfraRecorder: No realtime priority class possible

[^rooker]

InfraRecorder v0.41 on Windows 2000 gave me this strange error message while trying to burn a CD-RW:

...
16:08:37 The disc image was successfully created.
16:08:39 No realtime priority class possible.
16:08:39 Permission denied. WARNING: Cannot set priority using setpriority().
16:08:40 No realtime priority class possible.
16:08:47 Started to write disc in real write mode.
...

It burned the CD fine, but maybe I'll investigate the reason for this error...
