Linux DVB-S/DVB-S2 scan problem after Proxmox reinstall

Tue, 28 Jul 2026 11:31:59 +0000

Hi,
I'm experiencing a strange DVB-S/DVB-S2 issue with NextPVR on Linux.

Hardware

Linux4Media CineS2 Twin DVB-S2 (Micronas nGene PCIe, PCI ID 18c3:0720)
STV090x frontend
Firmware:

Code:
https://github.com/OpenELEC/dvb-firmware/blob/master/firmware/ngene_18.fw

Environment

Proxmox VE 9.2
Kernel: 7.0.12-1-pve
Debian 13 LXC
Docker
Latest Linux version of NextPVR

The problem
This setup worked correctly in the past.
After reinstalling my Proxmox host and restoring my environment, NextPVR no longer works correctly under Linux.
Using the same tuner hardware, NextPVR under Windows works perfectly. It finds all channels and Live TV and recordings work without any issues.
Under Linux, however, NextPVR is unable to find many DVB-S channels, especially the German private SD channels (RTL, SAT.1, ProSieben, Kabel Eins, Tele 5, etc.) during a channel scan.
Running the following command successfully finds all Astra 19.2°E (S19E2) transponders and channels:

Code:
w_scan2 -5 -fs -s S19E2 > channels.conf

The generated

Code:
channels.conf

contains all expected channels.
However, importing/scanning this

Code:
channels.conf

in NextPVR still results in many DVB-S channels not being detected.
I have also tested native on debian 12 linux and other Linux DVB applications.
For example, EasyVDR under Docker is able to tune and watch the missing channels successfully using the same hardware/sytem.

Summary

This setup worked correctly before reinstalling Proxmox.
The same tuner hardware works perfectly with NextPVR under Windows.
Code:
w_scan2 -5 -fs -s S19E2 > channels.conf
finds all Astra 19.2°E transponders and channels.
EasyVDR can tune and watch the missing channels.
NextPVR on Linux fails to detect many DVB-S channels during scanning, even when using a valid

Code:
channels.conf
.

Has anyone seen similar behaviour, or is there anything specific I should enable for debugging the Linux DVB implementation in NextPVR?
I'm happy to provide logs or test patches if needed.

NextPVR V5 client connection to KODI gone on 4 different TV's

Sat, 25 Jul 2026 19:06:45 +0000

Two weeks ago was watching Soccer on two different TV's using NextPVR client v5 via my Windows 11 PC. Today using the same credentials "NAME", Enabled, NextPVR Hostname = ip address of PC, 8866, and PINcode. All these items confirmed on all four of my TV's (and have not been changed) and the PC itself. None of the TV's NextPVR will connect to the server. The Local copy of NextPVR on the PC is working fine. I've switched network from Public to Private and back. I have maybe 5 or 6 hairs left on the top of my head. Log file from PC attached. Not sure where to find log file, if one, on KODI.

RSS support?

Advanced Recording Scheduling question

Fri, 17 Jul 2026 11:56:46 +0000

I was given a simple request by my wife.
"How do I record a program Monday, Wednesday and Friday skipping Tuesday & Thursday which are repeats of old programmes".
(without setting up 3 separate repeating recordings)

I said use the Advanced Scheduling but then hit a snag.
I don't see anything in the wiki that gives a full description of the syntax or options that are needed to be entered in the rule.

I went to Kodi as I thought there was a similar option there in the Timers but I only see a setting under Timer reminders not recordings.

Can anybody give me the syntax to use in the Advance Schedule settings please?.

VAAPI transcoding fails most of the time

Thu, 16 Jul 2026 00:56:31 +0000

Hey all,

I'm having an intermittent transcoding issue with NextPVR on Ubuntu 24.04 using VAAPI hardware acceleration. Most transcoding attempts fail, but occasionally they work without any changes.

Intel® Core™ i5-7500T CPU
Driver version: Intel iHD driver for Intel® Gen Graphics - 24.1.0 ()

I've verified permissions on /dev/dri/renderD128, the nextpvr user is in the video and render groups, and vainfo reports VAAPI support.
I've attached my latest logs (zip), which include both successful and failed transcoding attempts.
Any ideas on what I should check next?

I have NextPVR running on a Windows 11 machine hooked up to a Hauppauge WinTV HVR-950. It works fine for a few days. But then the guide quits updating, and it stop tuning channels. An error message says "Streaming Failed - Transcoder exited" when attempting to tune. If I restart the machine, it all comes back and works again for a few days before repeating the failure. Any idea what might be causing it?

Way to rip guide data?

Tue, 14 Jul 2026 16:26:37 +0000

I have some channels that wont load traditionally but work using direct links. Is there an easy way to use the guide data from the hdhr in nextpvr ?

I have to load these channels as iptv for them to work

#EXTM3U

. Would it be possible to do all channels like this and still pull guide data and assign them?

Unable to add Schedules Direct guide data

Tue, 14 Jul 2026 04:12:36 +0000

I am new to NextPVR, but I'm trying to get it set up as a replacement to an aging Windows Media Center CableCARD system with a Ceton InfiniTV. I've been using Schedules Direct successfully with epg123 and WMC for several years now, and I have an active subscription that I can't seem to add in NextPVR. When I log in to SD and attempt to refresh, nothing shows up under EPG sources. I think the logs are telling me that SD is blocking my attempt to pull lineup data, but I'm having a difficult time figuring out for sure where my issue is.

For background, I am running NextPVR in Podman on a Rocky 9 system (I have also tested in Docker proper, same issue). The container can access network resources, because it sees the tuners over the network and correctly scans for channels. I was working on getting this set up a couple weeks ago when I hit the SD snag and then let it sit for a long stretch until now, so any temporary (24-48h) blocks by SD should be over. I can provide any additional information that the logs don't show, obviously. Thanks in advance for the help!

UK-Crystal Palace Updated Frequencies

Sat, 11 Jul 2026 19:32:59 +0000

I set up NextPVR last week because I was fed up with the terrible delay with internet streams of TV, which is most annoying during the World Cup and Euros. If you're watching iPlayer (or, god forbid, ITVX) when England are playing, you may as well give up on being surprised by anything because everyone in a bar or watching over satellite/aerial will be approximately 5 days ahead of you.

Now that I have set up nextpvr feeding into dispatcharr, I can watch with between 2-8 seconds of delay (depends on SD or HD)! Perhaps not quite enough for a penalty shootout, but lightyears better than any other internet option. I did find, however, that the included frequency file for my transmitting station - Crystal Palace - is out-of-date, so I thought I might share my updated file here for anyone who needs it (DVB-T2 channels don't work on the npvr included one or the newest one on linuxtv.org because the frequency is incorrect in both, for example).

Server crash deleting pending recordings

Sat, 11 Jul 2026 17:58:52 +0000

Fyi, using yauiclient3 on my laptop, deleting some pending recordings for today that I didn't want. Server went down on the last one I was removing (6th or so).
Rebooted and grabbed the logs.

ADB for Mint

Sat, 11 Jul 2026 14:52:59 +0000

I switched my newer Dell laptop from Windows 11 to Mint 22 recently, and wanted a desktop app for ADB. I used to use adblink for Windows which worked fairly well but there was no option for Linux.

A brief search for an ADB gui for Linux revealed a program called AYA. Tried it out and was pleased with it. The program is a .Appimage which is like a Windows .exe. It's a standalone app so it works wherever you decide to put it. AYA has more features than adblink. I think it's easier to use as well.

Of course you can always use ADB from the terminal but this is easier and more fun IMO. Just thought I would share this for any Linux users out there.

Here is a screenshot of logcat with uidroid running

Guide data no longer updating after updating

Fri, 10 Jul 2026 08:43:56 +0000

A week ago I upgraded from a V6.x to V7.1.260616. It was working fine for a week but now I have no guide data as of 10am this morning. I'm guessing it was running off the guide data that was downloaded prior to the upgrade and that ran out.

It appears that it just no longer updates. A manual update does nothing, and I haven't changed anything else.

It should be pulling the guide data from the HDHomeRun tuner.

EPG sources shows a "Silicon Dust EPG" and below it DVB/ATSC EPG. I can't delete the Silion Dust EPG, delete butotn does nothing.

If I look under channels I can see all channels are mapped to the DVB/ATSC EPG.

I've tried all the usual stuff, reboots, service restarts, manual EPG updates etc.

Playback is fine.

Sudden failure of recordings

Thu, 09 Jul 2026 19:39:18 +0000

I am a long time user, current version 7.1.1.260616, about 3 days ago I noticed there was a noticeable slowdown when selecting programs to record or playback, then recordings started to fail, either they didn't finish recording or when I tried to playback they would play a portion of the recording then just close, I could replay and go to same spot (no Resume available) and play, but it would stop again. Then I started to get messages "Recording service stopped during recording" Then the App started to lock up and had to be rebooted, Then the web browser"localhost8866" would fail with "Can't find" error, I can reboot and everything works for about an hour then the failures start again.

I checked the disks, they seem to be ok, I recorded and played back using WinTV, everything OK, I tried running Setup again, don't think it did anything. If I try to playback recordings from NextPvr on another windows viewer they have the same problems.

DVB-C DeviceHost cannot tune channels on Raspberry Pi 5

Sun, 05 Jul 2026 21:06:40 +0000

Hello ppl,

Summary
I am running the latest ARM64 Docker image of NextPVR on a Raspberry Pi 5.
The DVB-C scan succeeds and channels are imported correctly, but Live TV and recordings always fail with:

Code:
No tuner was available for the requested channel.

The DeviceHost logs show:

Code:
Failed to get tuning params for (...) from /config/adapterX-DVB-C-channels.conf

The file is either never generated by NextPVR or the DeviceHost expects a different format than the standard DVBv5 tuning files.

NextPVR launches DeviceHost correctly.
Example:

Code:

-device:"adapter1/frontend0"

DeviceHost receives:

Code:

  DVB-C

  Arena Sport 3 HD

    514000000OFF

  2320

DeviceHost error
Immediately afterwards:

Code:
Failed to get tuning params for

(Arena Sport 3 HD)

from

/config/adapter1-DVB-C-channels.conf

Then:

Code:
HTTP 404

Finally:

Code:
No tuner was available for the requested channel.

Important observation
Originally there was no

Code:
adapter0-DVB-C-channels.conf

Code:
adapter1-DVB-C-channels.conf

inside

Code:
/config

.
The DeviceHost still expects them.

Experiments
I manually created

Code:
adapter0-DVB-C-channels.conf

adapter1-DVB-C-channels.conf

using:

DVBv5 format
frequency sections
standard NextPVR tuning format

Examples:

Code:
[514000000OFF]

DELIVERY_SYSTEM = DVBC/ANNEX_A

FREQUENCY = 514000000

SYMBOL_RATE = 6900000

INNER_FEC = NONE

MODULATION = QAM/256

INVERSION = AUTO

Parser accepts the syntax (no parsing errors),
but DeviceHost still reports:

Code:
Failed to get tuning params

which suggests it expects a different internal format.

Question
Should NextPVR automatically generate

Code:
adapter0-DVB-C-channels.conf

adapter1-DVB-C-channels.conf

after scanning?

Since scanning succeeds and

Code:
w_scan

works perfectly, the tuner and driver appear to be functioning correctly. The failure seems to occur only when DeviceHost attempts to resolve tuning parameters for live streaming.
Thank you for your help.

Nextpvr only showing DVB-T not DVB-T2

Thu, 02 Jul 2026 21:03:27 +0000

Hi, hope someone can advise me. I have the Hauppauge 3875199 wintv quad HD Pcie tuner, installed with Windows 11, with the latest drivers. This tuner is a DVB-T2 tuner, yet Nextpvr detects it as only DVB-T, why is that?

I'm trying to get ITV4 HD, but I can only get it in SD, Google AI suggests I need a DVB-T2 tuner? I can get other HD channels. So what can I do, to rectify this? I've attached the log files, hoping they'll help.

Many thanks,

G
