[mythtv-users] Setting up custom MythVideo Grabber

[ajp at cantabrian.co.nz]

As a follow up I am starting to make progress on this and one of the big
things was that the RPM which I was using seemed to miss a dependency
"python-lxml", without this MythTV didn't list any python grabber scripts
:-(

So I think I am slowly getting on track with this thanks for the help
everyone

Not quite. The script only returns data in the XML format defined on this
page. The Video Library parses that data, and handles updating the database.

The metadata setup in mythfrontend will scan for executable files in the
expected location, and check to see if they return the expected "version
output" described on the above page. It presents a spinbox, allowing you to
select which of the discovered grabbers you want to use.

Scripts are stored in $PREFIX/share/mythtv/metadata. I don't know off hand
what the value of "$PREFIX" would be on a Fedora system. Likely
possibilities are /usr or /usr/local.
