I have 3 HDHomeRun Connect boxes connected to a single antenna, so 6 tuners total. When I'm watching live TV via Kodi, NextPVR often steals the live TV's tuner for a scheduled recording, even though there are other tuners available, causing the TV to freeze with a Tuner No Longer Available message. NextPVR doesn't seem to be properly reusing tuners, often using 2 or more tuners for recording different shows on the same channel. Below is an example of this poor behavior, which I have tried to document as best as possible, with the logs from the evening of February 17, 2016:

It was smooth sailing until I changed the channel at 8 pm to PBS to watch NOVA. The live TV briefly changed channels, using the same tuner before and after the channel change, but then ended itself for some other reason. It was a simple matter of resetting Kodi and tuning back to the channel to successfully watch it. However, the live TV lease on the tuner was ended twice more that night before it was preempted by other recordings that shouldn't have preempted it, once at 9 pm and again at 10 pm. Here is a more detailed report:

Tuners available, ordered by priority, with corresponding NDigitalHost log names:
10438DEB-0: ndigitalhost-29.log
10438DEB-1: ndigitalhost-31.log
10422AD6-0: ndigitalhost-21.log
10422AD6-1: ndigitalhost-23.log
104259B8-0: ndigitalhost-25.log
104259B8-1: ndigitalhost-27.log

Below are short-hand records of the Settings > Status screen at critical time points, as reconstructed from screen captures and the NDigitalHost logs, with notes on the channels of each tuner and questions about its behavior:

8:08 PM (constructed retroactively from NDigitalHost logs):
Why wasn't the live TV stream leased to tuner 10422AD6-1, which was already tuned to the requested channel?

Scenario: 1 minute pre padding, 2 minute post padding. This is with one HDHomeRun Prime. One tuner is set to record from 9-11, a second is recording from 9-10. At 10 two shows on two new channels are set to record, one just takes the third tuner 1 minute before 10, the other keeps trying to allocate a tuner a few times a second, and finally succeeds right on the hour. While the tuner does swap channels and starts writing a new file as soon as the previous show is done, minus the post padding, the file for the 9-10 show continues to be written to, causing the file to have two minutes of another channel on it, this causes playback issues in third party players. Windows file details says the file is 10:02:16. In MPC-HC, which is my main player, I can not seek in the program, and in WMP, every section of the show is repeated, and VideoReDo complains about no data found. The way to fix this is to cut the last two minutes off of the recording, the stuff from after the channel switch, which I can do with an old program that only partially supports mpeg 2 TS files.

I realize that this is a byproduct of the multi-record feature, which is great, and the main reason I am using NextPVR over a different program, but would it be possible to disable it when the tuner has to swap channels?

Thanks.

I have attached the only program that I have been able to use to see the error causing last two minutes.

New to NextPVR and I actually have it up and running on my Windows 7 x64 machine

Machine is Intel NUC D34010WYKH1 i3 processors
8 GB of System RAM
Samsung 850 EVO mSATA 500GB SSD
2 each WinTV-dualHD USB TV Tuners (4 tuners total)

I am trying to find if NextPVR will support this configuration?

I can record one channel and watch another, but I never see the other tuner light up or activate itself

The goal is to be able to record 3 programs while watching a forth.

Any assistance on tuning to make this possibly work would be greatly appreciated.

Thanks,

I'm building a pvr with a laptop. I'm about 45 miles from towers. I bought a cheap USB tuner but it only gets about half the channels my tv gets (they are on the same splitter). So that's going back. Looking for something with a strong tuner. I'm thinking about:

HAUPPAUGE 1595
Pro - Well known name brand
Con - USB. Does tuner get enough power to pull in weak stations?

Or

HDHomerun Extend
Pro - I assume it plugs in to wall. More power for tuner?
Con - Expensive.

Any suggestions? Thanks.

Hi ALL,

I'm having a problem when I'm done watching a recording and I either use an IR remote's Exit or Stop button or when right clicking the mouse and selecting Main Menu to get back to the main menu 99% of the time NPVR's window goes black with nothing happening and when I try to click on something (even though nothing is showing) Windows 10 says its not responding and I have to force it to close. Similar to that when I watch Live TV if I try to get back to the Main Menu without changing channels I get the same black screen as above. But in this case if I change channels and then go back to the original channel I can successfully get back to the Main Menu.

Everything else is working nicely so I'm very disappointed that I'm having this problem as I am so close to having NPVR becoming a good replacement for WMC. The system is a Dell Zino with a Hauppauge UBS TV tuner running Win 10 64 bit. I also have Haup's Win TV v8 installed and that runs with no problems. And lastly I have a desktop PC with the same software but Haup add-in card TV tuner and I do NOT get the black screen problem there!

Any help would be GREATLY appreciated!!

My cable provider is using an od combination of MBd (6875), QAM (256) and Freq (starting as low as 306000 kHz), which means that I only can find 3 channels with a manual scan on Freq 306000.

Is it possible to edit a config file, to make NextPVR scan all Freq from 306000 and up, with MBd 6875 and QAM 256?

Hey all,

I'm looking or a little bit of help. I am running NPVR on Win 10 with a Ceton InfiniTV 4. A far as setup goes it pretty basic. All of my channels have worked from the start with no problem. But about a month again some of my channels started having problems. To give you an example, if I turn to Comedy Central (channel 772.1) NPVR hangs and then comes up with "The Tuner you were using was required for a recording" even though there is nothing else recording.

For the recording I have setup on this channel it creates the files, but they are 0KB. There are a few other channels that I have come across that are doing the same. All of my other recording work just fine.


Thanks for any help.

Hi.

My setup is simple: Windows 7 Ultimate - KODI - nextpvi

I am trying to record live tv from kodi. I do not have any other tuner in my PC.

I set up kodi to enable PVR Service. I also set nextpvr which seems to be connecting to the IPTV (getting Channel-1 udp://224.100.0.1:9050)

Yet, when I click on LIVE TV in nextpvr I get a black screen (I'm not sure what channel-1 is)
And the record icon in Kodi (the one in the form of a CD) is grayed out.

Can someone pls help me record!

Thx

I've been running nPVR for a while now - currently on v3.5.7 under Win 7 using FreeSat.

From time to time the powers that be move one or more of the channels (Channel 5 is a recent case in point) and in the past I have emptied the EPG, deleted all the channels and done a scan to fix the problem.

The pin in that is having to go through the channels deleting all the rubbish.

I ask myself "Is there a better way ??"

Any suggestions welcome
Dave

I have a number of channels that are no interest to me, so I deleted them, however when I do a rescan they appear gain (as o would expect)... Is there a way to disable a channel? So that I can hide these channels but don't have to re-delete them after a re-scan??? I do appreciate that re-scanning channel is a regular task....

Edit : Sorry meant to type "NOT a regular task"
