For simplicity, let's just assume that FTA channels have a CA ID of '0',
while encrypted channels have something else. Any value between '1' and '255'
(including) would have to be set manually, which I assume you never did.

The 'device' is the receiver (the thing you connect the antenna cable to).

This one has H.264 video (5131=27).

This is MPEG video (2931=2).

Also MPEG video (671=2), but encrypted.
You will need a CAM with a proper smartcard to decrypt this one.

Things to test:

- Can your output device play MPEG video?
   Some devices (like the Raspberry Pi, for instance) require a separate license for that.

- Do you receive any data from "NHK WORLD-JAPAN"?
   Check the log entries for "buffer stats" when switching to that channel, remaining on
   it for a while, and then switching to a different channel.

- If you record "NHK WORLD-JAPAN", does it produce a non-empty file?
