WinTV Dual HD - Only One Tuner

General Discussions Plex Features

Hi,

I have recently bought a WinTV Dual HD tuner to use with Plex.

My OS is Elementary OS (Ubuntu 16.04).

I was having some difficulty getting it to pickup HD channels but have solved it by booting with the patched 4.4 kernel that is installed when following the Hauppauge Linux guide: http://www.hauppauge.com/pages/support/support_linux.html

However I can’t get it to appear as 2 tuners. In the logs I see mentions of merging 2 tuners to one whereas before the kernel switch it was saying merging 1 tuner. I am thinking that since I setup the DVR device before using the patched kernel, it is persisting some settings.

I have deleted the device several times but it still comes back as a single tuner. Any ideas? I don’t really want to install Plex from scratch again and I’m not even sure that is going to fix it.

Thanks

A dual tuner will not appear as two discrete tuners. It’s one device which can record two things simultaneously.

You should ungrade your kernel. The old driver supports only one tuner. Search on github.

Yeah I get that it will only appear as a single device. However it explicitly says on that device ‘1 tuner’ and I can only play one channel concurrently.

Upgrading the kernel? From the documentation only 4.4 is supported for my Ubuntu version. Will this not work with a dual tuner? I need to test but I think outside of Plex it is seen as 2 tuners.

Thanks for trying to help.

The Ubuntu media tree kernel from Ubuntu kernel + LinuxTV media tree + Hauppauge patches : Brad Love is a must for this device. Even upstream 4.18 Linux does not work currently. Important patches will be included in 4.19 :frowning:

Just restart PMS after running the media tree 4.4 Kernel and reconfiguring Plex DVR. The second tuner will be picked up eventually.

Hi, I’ve reconfigured the device, restarted PM’s and restarted the machine it runs on. Nothing has made the device appear with 2 tuners.

I’ll send some logs when home but they mention something like ‘merging 2 tuners to 1’.

Thanks

Oh and I’m using the 4.4 mediatree kernel. I’m sure of this because before using that HD channels were not being picked up.

I’ve tested using the plex docker container (same version of plex I am running normally) and the device is showing as having 2 tuners. Also 2 channels can play concurrently.

This is making me think the device is not fully removed when I select to delete the device within the plex UI. Are there any files that may need deleting in order to fully remove all traces of the device?

I can obviously switch to using a docker container but I don’t really want to transfer all of my settings, etc…

Thanks.

i_ata89, I believe you are correct.

Here’s what I did to resolve the issue on my end:

  1. Find the PMS database, per-platform instructions here: https://support.plex.tv/articles/201100678-repair-a-corrupt-database/

  2. Stop Plex

  3. sqlite3 com.plexapp.plugins.library.db
    sqlite> delete from media_provider_resources where identifier = ‘tv.plex.grabbers.tunerservice’;
    sqlite> commit;
    sqlite> .exit

  4. Start Plex

Re-add the Tuner. After this, it came up as 2 tuners as expected.
