Raymond,

I have applied your patch - the script now successfully calls the
transcoder, but fails at the next step:

kerr at MediaServer:/usr/share/doc/mythtv-backend/contrib/user_jobs$
/usr/share/doc/mythtv-backend/contrib/user_jobs/x264_inplace.py 1340
Traceback (most recent call last):
  File "/usr/share/doc/mythtv-backend/contrib/user_jobs/x264_inplace.py",
line 96, in <module>
    main()
  File "/usr/share/doc/mythtv-backend/contrib/user_jobs/x264_inplace.py",
line 88, in main
    runjob(jobid=args[0])
  File "/usr/share/doc/mythtv-backend/contrib/user_jobs/x264_inplace.py",
line 19, in runjob
    job = Job(jobid, db=db)
  File "/usr/lib/pymodules/python2.6/MythTV/database.py", line 284, in __init__
    DBData.__init__(self, data, db)
  File "/usr/lib/pymodules/python2.6/MythTV/database.py", line 153, in __init__
    self._pull()
  File "/usr/lib/pymodules/python2.6/MythTV/database.py", line 342, in _pull
    DBData._pull(self)
  File "/usr/lib/pymodules/python2.6/MythTV/database.py", line 169, in _pull
    raise MythError('DBData() could not read from database')
MythTV.exceptions.MythError: DBData() could not read from database


Any help would be appreciated,
