Hi plex forums,

The Live TV and DVR is not working. It cannot find any channels when using DVB-C. When using DVB-T2 it does work. I suggest that the network id or so is incorrect, and that the digital signal is not detected properly?

I hope to learn how to solve something like this.

It used to work 2 years ago. Because it had all kind of problems I stopped using it. Now, I want to use it again (assuming problems would have been solved) but it is again not working.

Can some plex employee tell me what it could be, or can they solve the problem.

Note: (Ziggo has on the same frequencies sometimes multiple network-ids depending on the location fUPC or fZiggo). Maybe that can cause problems? Ziggo has done two thjngs the past few years.

  • It has merged two networks with different network-id and frequencies with different backbone
  • It has discontinued analog broadcast all together, including radio and TV, replacing it with unencrypted digital and encypted digital signals with different network id and frequencies for each.

In summary;

DVBC only digital
Network-id 4444 is unencrypted
Network-id 5555 is encrypted, and you’ll need a CI+ module
fUPC area (unencrypted) is network frequency 474, symbol 6900 and modulation 64QAM
fZiggo is different
fUPC encrypted is different
fZiggo encrypted is different
and all is different depending on postal code

You can check here the settings;

It doesnt seem to work on any frequency that is available on the plex settings. I would want to have the option to manually edit the settings for the DVBC. It is not possible to get any signal through any presets.

Awaiting your response,

All I can give you is this: Bug in Scanning DVB-T2 with QAM256 in UK - #2 by OttoKerner

You need to find the right .ini file which was used before. Then make the changes Re: frequency and symbol rate etc for the new channel setup.
Then delete the tuner in plex and set up a completely new one.

Keep in mind that Plex will not access encrypted channels or those which have been marked as “recording prohibited”. (which can possibly mean all channels within a station bouquet)

The ini files are located on Windows in here:
C:\Program Files\Plex\Plex Media Server\Resources\Tuner\Shared\scanners\
and on Linux they can be here /usr/lib/plexmediaserver/Resources/Tuner/Shared/scanners/ (or whatever equivalent location your particular platform uses).

Then I think I am out of luck. They have mixed channels you are not allowed to record with ones you are allowed to record in the same network id, while one network id is unencrypted and the other network id (on the same frequency) is encrypted. I have tried to change the symbol frequency, but no luck. I really need to be able to also set the network id if I want to be certain.

I am on fUPC as well and have problems setting this up in Plex as well. I noticed using HDHomerun Setup that you need to have a different config to scan for channels. Use QAM265 instead of QAM64, maybe this helps.

fUPC area (unencrypted)
network frequency 474000
symbol 6900
modulation 265QAM

You mean QAM256? I tried that.

yes QAM256, cannot get it to work either…

Like I said in my initial post, I think I have to be able to set network id.

I am unsure whether this has any influence. Though I haven’t decoded what role the number in the file name of the .ini plays. Maybe that is the network ID?

Yes but when using the hdhomerun setup you do not use channel id as well. Only frequency, symbol rate and qam.

When using 474000,6900,Qam64 i only get one channel, testbeeld
When using 474000,6900,Qam256 I get all channels

In plex, I am now playing around with a new transponder with qam64 and get 5 channels…

I cannot test at this time. But, with network id 4444 you should get atleast 25-30 channels for tv. If you get 5-6 channels then clearly something is not right. I do know that they have changed their frequencies (for channels individually not so long ago)

yes, got it to work. Need to do some testing but will update soon.

SO here goes, this took me a couple of hours to find out.

BEFORE YOU START
make a copy of com.plexapp.plugins.library.db in C:\Users\Username\AppData\Local\Plex Media Server\Plug-in Support\Databases
If you screw anything up or need to rescan simply restore the db. Pex remembers the DVR, HW and Channels and else you are unable to start over.

I created an additional Transponder ini file and I was trying for hours to get it working in Plex using the following data:
[SATTYPE]
1=4444
2=DVB-C fUPC Ziggo
3=NL

[DVB]
0=1
1=474000,6900,QAM64

I tried almost every combination also knowing that Sillicondust mentioned to use QAM256 (as this works in their HDHomerun Setup scan.
Looking at the Plex logfiles I only saw the above combination gave me back 5 channels (4 data channels and 1 TV channel (Testbeeld)). All other gave no channels or tuning errors.

I looked into adding channel IDs but there is simply no option to do so.
I started looking into the other Transponder files and found an old copy of my DVBLink installation. There was a custom transponder with Ziggo information which was similar to whats above.
Then I noticed some transponder files had a lot of frequencies listed and figured out that it could be that some of the data channels where sending our additonal frequency lists.

I started the HDHomerun Congi GUI tool that shows channel quality information and noticed it also shows frequencu information. using HDHomerun app I switch some channels and notced the frequency changing per channel. I noted all frequencies and created a new transponder file in C:\Program Files\Plex\Plex Media Server\Resources\Tuner\Shared\scanners\dvbc\transponders

I named it 4444.ini4444.ini but you can name it anything you want as long as the 1=4444 is equal to the file name

22=514000,6900,QAM256
23=538000,6900,QAM256

This have me back all channels.

I now need to find a way to get EPG data and connect it to the channels.

Okay, I will be home in like an hour, and I will test with my hauppauge dbc dualhd or what it is called. Thanks already for this very detailed information. I will post in next few hours how it went.

I did this. Leaving out the V is deadly for the channels in my case. Any idea what V means?

Thank you very much. I dont have a hdhomerun, so I would not have been able to find any logs. I have a hauppauge wintv-dualhd, and after this it is finding the channels and it plays them.

It is explained in my link above. It needs to be there (even though it’s useless for terrestrial), or the parser will confuse the data columns.

Nice! No idea what the V does. Also, the logs where from Plex.

Where do you get your EPG data from?

It seems to be an option after the scanning if you use a hauppauge wint dualhd.

Do you have a problem with channels stopping after lets say 4-5 minutes?

Because, that is why I stopped using live tv 2 years ago. It buffers, plays for 4-5 minutes, then it stops and the stream wont recover correctly…

EDIT:

Probably it has to do with transcoding profiles. I will see if I can fix that…

for some reason I dont understand, in the release from 16-09-2024 the live tv works as expected. Maybe you can look into this?

I will post this in the preview channel aswell…
