Describe Job Queue here.
There are 4 customizeable jobs you can have in the job queue. These can be configured by running mythtv-setup. In mythfrontend, you can then configure myth to allow specific jobs to run on the host, as well as configure those jobs to run.
Commercial flagging appears to be part of the Job Queue. The status of the Job Queue is visible on mythweb under "Backend Status".
