Nope you haven't not yet, the fact that you are stilling seeing the 'Tuning'
message means that no packets have yet been captured.
See my other mail on hopefully solving this..

With the generic record plugin you need to specify a script to run that
will do the recording. The script gets passed a whole load of parameters
(configured by local_conf.py). You need to in that script use the
hdhomerun config program to configure the device and then capture the
stream.

I've attached a knocked together a HDHomeRun recording plugin, drop this
into the freevo/tv/plugins directory under the python library directory
where freevo was installed (something
like /usr/local/lib/python2.7/dist-packages/freevo/tv/plugins).
Then use this plugin instead of the generic record plugin.
Hopefully it should do everything that is required to record from the
HDHomeRun. If it works I'll drop it into the main repo.
Cheers
