Thank you for your reply.  You must be correct because I removed 
everything from that line and queued a job.  And indeed, it's running.

Sorry to be so dense but now I am at a loss as to how to create a 
wrapper script.  I kind of get it in that I will write a script that 
calls mythcommflag wtih my 'ionice' command in front.  But what I'm not 
getting is how I do that and let all the other information mythcommflag 
needs to pass through the wrapper.

I found this but it seems to be much more that I need and don't fully 
understand it.  However it seems that by taking this script and 
modifying, I somehow I could not commflag newscasts as an example in 
addition to getting my ionice command passed?  This is something I 
wished I could do for a long time is not waste the CPU cycles 
commflagging newscasts or sporting events.  Anyway, this is what I found:

I'd appreciate a nudge to get me on track.

Thanks,

Drew
