Hi, below a short overview about MythTV and
python grabbers for television and videos:

1) The default grabber script paths are determined by the
sharedir  = installprefix + "/share/mythtv/"
and the default script location (see item below).

2) Those default locations can be overwritten by specific settings
of the frontend. If not present, they point to their defaults
"TelevisionGrabber" -> metadata/Television/ttvdb.py
"MovieGrabber" -> metadata/Movie/tmdb3.py
An error in the log like
"MythSystemLegacy() command not executable,
eno: No such file or directory (2)"
might occur, if the setting for that grabber is wrong or empty.
See Frontend: Setup->Artwork and Data Sources
A search in the mysql settings table may be useful:
 select * from settings where value like "%Grabber";

3) The grabber scripts itself must be executable and the
first line (shebang) must point to the installed python version.

4) The scripts can be tested by running them with the
"-t" parameter from the command line,
e.g.: "/usr/share/mythtv/metadata/Television/ttvdb.py -t"
The result is either a traceback or the message
"Everything appears in order."
Tracebacks usually give hints about missing python packages.

5) Pythonpath
If the python package "MythTV" is not installed in its standard
location like "/lib/python<version>/site-packages/MythTV",
the PYTHONPATH environment variable must be set to the folder
containing the "MythTV" python package.
