Tvheadend

A very precise question... It's a question at this time, but maybe I can turn it into a tutorial with your help. Thank you in advance!

I already have a solution to play HDHomeRun ATSC channels using mplayer, so I know that it works under FreeBSD. I can even record live TV using the capture feature of mplayer. However, I would love to use the Scheduled Recorder feature of Tvheadend.

Tutorials I found were really hard to follow and confusing because they were from a different Tvheadend version, not specific to only Tvheadend, and dealt with Linux intricacies.

1)
So, what I have installed is the multimedia/tvheadend Freebsd port, more precisely, it's version 4.0.8_1. At first, it wouldn't build because of missing functions during the linking phase. For example, the missing inotify_init1() function called in fsmonitor.c. This error is addressed by deinstalling the devel/libnotify FreeBSD port.

2)
Now that Tvheadend builds nicely, I run it in a user terminal. A nice looking web page is linked to port TCP 9981. I browse through the tabs to familiarizing myself. Lots of options I'm not exactly sure what they are all about.

3)
The tab CONFIGURATION -> DVB INPUTS -> TV ADAPTERS is where the HDHomeRun device is detected, as well as its two tuners. Next to the TV ADAPTERS tab is the NETWORKS tab to create network configurations. Tuners can then be assigned a network. Next to the NETWORKS tab is the MUXES tab to scan the tuner channels. Lots of options there too.

This is where my journey ends! I don't know how to have the available channels scanned and listed. (SCAN RESULT: FAIL) The PLAY link in the MUXES tab opens a blank VLC.

If it can be of any help, these errors are printed in the terminal:

I know that auto:0 is not good. How could I specify the system to use, for example:
:5004/auto/v5.3
If I watch it weeknights 30min. after midnight, I'll be watching THE TWILIGHT ZONE in black and white. ;-)
