This error message means mythbackend can't find mythcommflag, so even
though mythcommflag is in _your_ PATH, it evidently isn't in the PATH
of the user running mythbackend or the script that is running
mythbackend.

Search for this error message on the mailing lists and you'll find
several solutions.

This has been explained quite a few times on the mailing lists, so
I'll let you read the explanations when you search for the error
message above.

It was, quite a few times. :)  Previously, the mythcommflag
executable did not actually get called by mythbackend,
mythbackend directly ran the commercial flagging code internally.
This had the negative side-effect that if there were any problems
in commercial flagging that might cause a segfault, etc. whether
the issue was in the flagger, player, etc., then the backend would
go down.  In order to isolate the flagger from mythbackend, after
the JobQueue was created, I modified the JobQueue to call out to
mythcommflag rather than running the flagger code inside mythbackend.

You can either manually delete them or you can take the ?easy? way
out and go into the JobQueue page in mythfrontend's status screen
and delete them from there.  Select the item to delete and pick
Delete from the popup menu.
