[mythtv-users] Lossless Cut and removing recordings

Fri Nov 9 20:38:11 UTC 2012

Hi Doug,

Sure enough those steps do not work.  Here is the python output and a
couple of lines from the backend log.

Cheers
Stephen

>>> recorded_list =
list(db.searchRecorded(basename="8940_20121109002000.mpg"))>>> recorded_list
[<Recorded 'A Little Later','2012-11-09 01:20:00+01:00' at 0xa095e3c>]
>>> recorded = recorded_list[0]
>>> recorded
<Recorded 'A Little Later','2012-11-09 01:20:00+01:00' at 0xa095e3c>
>>> program =
be.getRecording(chanid=recorded.chanid,starttime=recorded.starttime)
>>> program
<Program 'A Little Later','2012-11-09 01:20:00+01:00' at 0xa099dac>
>>> result = be.deleteRecording(program, force=True)
>>> print 'The result should = "-1" which means success. Result(%s)' %
result
>>> recorded_list =
list(db.searchRecorded(basename="8940_20121109002000.mpg"))>>> recorded_list

>>> print 'The recorded_list should be empty if deletion worked.
Recorded_list: "%s"' % recorded_list
The recorded_list should be empty if deletion worked. Recorded_list:
"[<Recorded 'A Little Later','2012-11-09 01:20:00+01:00' at 0xa099e3c>]"
