I've now managed to debug the external recorder on the command line

/usr/bin/mythexternrecorder -v all:debug   --conf  
/usr/local/share/myPVR/iptv/vlc-nz.conf


I can then send commands to check on the configuration

So I don't have a valid Tuner and I can't tune or channel scan under
mythtv-setup.

I'm using a config for VLC based off the examples in the Wiki which don't
specify a command under TUNER

https://www.mythtv.org/wiki/Example_Configuration_files

Can someone provide a known working vlc.conf I can used as a template.
I've tried modifying the entry to

command=echo %URL%

Which means I get a valid Tuner reponse but I still can't tune in correctly.
