The problem is that if you have separated frontend and backend, you
need to install mythnetvision in the frontend. But the python scripts
resides in the backend.
I had problems to execute this (in the backend):
# /usr/share/mythtv/internetcontent/youtube.py -v
The subdirectory "nv_python_libs/youtube" containing the modules
youtube_api.py (v0.2.0 or greater),
They should have been included with the distribution of youtube.py.
Error(No module named MythTV)
After installing python-mythtv and python-lxml I can select the
desired grabbers in the frontend. This the output in the backend:
# /usr/share/mythtv/internetcontent/youtube.py -v
