Name: mythtv_rerecord_check.py

Author: Kane Tse

Purpose: This Python script is intended for use to detect zero-length recordings, delete
them from MythTV (database and filesystem?) and re-schedule for recording.  

Version: 0.1-alpha

Usage: It is intended for use as a cron job.

Warning: This script is an untested alpha-release.  Use at your own risk.

Requirements: Intended for use with Python bindings for MythTV-0.24

Date Written: 2011-03-06

Bugs: If the tuner is not functioning properly, the call to reschedule may result in the
attempting to recording the same show on the same non-working tuner.  This may be a 
good thing if the buggy tuner is functionning intermittently.
