Comparing vs. another device would be a good place to start, even if it's just putting the same game on your phone or tablet while watching on TV. The GTV Streamer is unfortunately one of the worst streaming devices in currently on the market and suffers from a lot of playback reliability issues.

The only potential good thing to come of the Paramount/WBD merger is that Fubo carries Paramount channels but not WBD channels. If they can get TNT then they suddenly become perhaps the best option for NHL fans. Their app has to be better than DirecTV's because I don't think there's any way it could ...

We have confirmed a bug in the display of the original air date on various platforms. Updates are being worked on.

I am showing it currently has data for MovieSphere Gold, which appears to be correct given the MovieSG name of the channel. West data is showing on 31.4 again as it appears it should be.

Unfortunately our guide provider does not have data for Croatia.

What is the device ID for your HDHomeRun?

+25 dBmV will likely overload if you have a lot of channels. Try to get to around 0dBmV at the input to the HDHomeRun, so just work back from there to account for splitters, long cable runs, etc..

In short, no there is not a way to change the names of the channels. There are a lot of rules in the CableCARD device specs about using the data coming from the CableCARD with the obligation being on the cable provider to supply accurate data. We do have data for most of the channels that overlap ...

What is the device ID for your HDHomeRun? We can update the guide listings.

You would either need to set the speaker configuration in the HDHomeRun app to passthrough or connect the PC directly to the receiver via HDMI. S/PDIF is bandwidth-limited and can only carry DD, DTS, or max 2 channels of PCM audio.

Is it the original model that has the loop-style elements where the transformer attaches:

Or the newer model that just has the blades:

What type of connection are you using between the PC and receiver?

The box is doing the decoding. It does not explicitly list an AC-4 decoder, but instead the app has to send it the audio as if it was going to do passthrough and then it decodes. This is common in devices based on the Amlogic SoCs. It should provide 5.1 where available.

There is no customer-visible diagnostic mode, but if you enable the sending of diagnostic data in the gear menu HDHomeRun app, watch an ATSC 3.0 channel, and reply back with the device ID for your HDHomeRun, we can check the logs to see what AC-4 mode is in use.
