This is the Python program I use to PRINT damaged
recordings.

The last 5 lines are additions. It will
remove *one* title/subtitle of your choice. If it works
as expected, then remove the 'if ...' and adjust the
indents on the remaining lines.

But like Mike just said, be careful.

$ cat damaged.py
#!/usr/bin/env python

"""
Print info for recordings marked as damaged.

import sys
from MythTV import MythBE, MythDB

try:
     DB = MythDB()
     BE = MythBE()
except IndexError:
     sys.exit('Unable to connect to the backend, aborting.')

HEADING_PRINTED = False

for recording in DB.searchRecorded():
     # pylint: disable=maybe-no-member
     pgm = recording.getRecordedProgram()
     # pylint: enable=maybe-no-member
     if not 'DAMAGED' in pgm.videoprop:
         continue
     if not HEADING_PRINTED:
         HEADING_PRINTED = True
         print '\n  {:30.30}  {:15.15} {:17}  {}'.format(
             'Title', 'Sub Title', 'Starttime', 'Video Properties')
     print '  {:30.30}  {:15.15} {}  {}'.format(
         pgm.title,
         pgm.subtitle,
         pgm.starttime.strftime("%b %d %Y %H:%M"),
         pgm.videoprop)
     if pgm.title == 'Some Program Title' and \
             pgm.subtitle == 'That You Want To Test With':
         rec = BE.getRecording(pgm.chanid, pgm.starttime)
         print 'Deleting: {} ({})'.format(pgm.title, rec.filename)
         BE.deleteRecording(rec)

Recordings won't vanish immediately, just like find_orphans, so
don't worry if they still appear to be there.

Or, you could use the Services API:

curl yourbackend:6544/Dvr/DeleteRecording?RecordedId=xxx\&AllowRerecord=True
RecordedId can be replaced by ChanId and StartTime
