hello,

i have set up cdrecord on my sysem allowing certain privileged users part of 
a "cdwriter" group to use the relevant SCSI devices so that they may write 
cd's. although this seems to be running well, users who are not root all get 
the following warning when writing cd's:
---
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.
---
which device must i allow them to use in order that this scheduler can be 
utilised in cdrecord, and thus preventing buffer underruns under certain 
circumstances?

any help appreciated
Sam, Ireland
