I got the update to 4.2.1-51~g04b6e3c today.
With this verison the TV recocnice TVH but still fails searching channels.
There is no connection logged from the TV.
I'm not sure if this is a port based error or something else.
The configuration the TV shows is attached.
Edit:
I tried with minisatip on port 554 and got the same problem.
Server will be detected but no channel scan.
