Hi all,

I’m new to NextPVR and have been enjoying using it. However I’m currently having a couple of minor hiccups/problems with my setup, and was wondering if anyone could help please?

I’m in the UK and currently have: A PCI-E dual tuner card using freesat (DVB-S) and just recently added a Hauppauge dual USB tuner using freeview (DVB-T).

Problem with EPG listings
[/B]At present I’m missing EPG listings for the following channels:

ITV4+1
ITVBE+1
5Star+1
5Spike+1
Sony Movies+1
True Crime+1
Paramount

Previous to this I was missing a lot more of the EPG listings for my channels, but found an old post on the NextPVR forums mentioning changing the “SID:” number in channel details. After looking online for the SID numbers, this fixed a lot the missing EPG info for many channels but unfortunately not the ones listed above.



Problem with artwork and recent recordings
Lastly just yesterday Kodi has stopped displaying any artwork/metadata in recent recordings (have attached screenshot below). I installed & updated to NextPVR release 4.2.4.190307 yesterday afternoon and I can only assume I’ve made a mistake in the settings somewhere. Film/TV Series Artwork still appears in the “EPG listings” and also “timers” but is missing in recent recordings.

For some reason all previous artwork which was displayed in recent recordings has also been deleted. (I appreciate that in some cases artwork isn’t always found for some Film & TV programs, however have tried recording Time Team today which normally has artwork and recent recordings is still blank for this programme unfortunately.)

I have “show metadata screens in recordings” ticked in the NextPVR Settings, along with "Download TV Guide Artwork" selected on the NextPVR Kodi Addon.




If any further information is required please let me know and will be more than happy to provide it.

Many thanks in advance for any help/assistance anyone can offer me.

*** Problems with overlapping recordings

About a year ago, I was in this forum reporting a bug where npvr was
creating defective recordings. Although the records could play black
within npvr itself, they could not play using wmplayer. With vlc they
do play, but the time fields were all zero and the hotkeys don't work,
although the progress bar still works.

This bug started happening when I switched from Windows media center
to npvr in 2016. It continued when I switched from a Ceton tuner card
to an HDHomerun. In the last year, there have been several new
versions of npvr, but the problem has not disappeared.

In the last month, I changed from a Windows 7 system to a new computer
running Windows ten, and the problem persisted.

So that eliminated almost all the variables. The bug did not occur
with media center, but it did with npvr in numerous configurations --
ceton vs hdhomerun, Windows 7 vs windows 10.

The only possibility left is that this is a bug in npvr.

During the last month I started looking at specific situations when it
happens and when it doesn't, and this has led me to find exactly what
the bug is in npvr.

Here are two scheduled programs:

21:29:00+0:31: 4 25 REC Fam [Fam.S01E09.Ocean.View.ts]
22:00:00+0:30: 61 25 REC Broad City [Broad.City.S05E07.Shenanigans.ts]

Fam was recorded from 21:29 for 31 minutes on tuner 25, while Broad
City was recorded from 22:00 for 30 minutes on tuner 25. Fam is on
channel 4, and Broad City is on channel 61. So, theoretically, tuner
25 switches from channel 4 to channel 61 at exactly 10 pm.

Here's the NPVR status as of about 30 seconds past 10 pm:



This state of affairs goes on for two minutes.

Notice that BOTH programs are recording, even though they're on
different channels using the same tuner. There is no planet on which
that make sense.

The result is that the meta-data for BOTH recordings is wiped out.
This is the bug that's been occurring for years.

This is due to pre-padding (defaults to one minute) and post-padding
(defaults to two minutes). Pre- and post-padding is a GOOD thing when
you're recording the same channel, but is a BAD thing when you're
changing channels.

To fix this bug in npvr requires a new "overlap algorithm":

• If one recording is overlapping the next recording on the same
  tuner on the same channel, then overlapping is wonderful.
  
  
  
• But if they're on different channels, then the end time of the
  first recording and the start time of the second recording must be
  adjusted so that there's a gap of a few seconds between them, to
  give the tuner a chance to reset. This has to override the pre-
  and post- settings, since it never makes sense to record two
  different channels on the same tuner at the same time.

Those of you trying to record Deuschland 96 on More 4 Freesat, may have noted that Sky/Channel 4 have encrypted the standard transmission.

A non encrypted version of the channel can be found on 10936V 22000 56 which is missing from the 0282.ini file .

I added the following line to the file 15A=10936,V,22000,56,DVB-S,QPSK and all appears to be working.

Apologies for starting a new thread but I think it is worth doing so now that I have a reasonable idea of the blaster utilities and commands required to operate my IPTV STB.

What I didn’t realise was there is a whole industry surrounding IPTV channel zapping (it even has a name!) with lots of research papers etc etc.

Anyway, whilst sub has patiently explained the whole IR Blasting process is SLOW and the technology hasn't changed i.e. it remains a crude simualtiuon of someone pressing a remote, the thing I still don’t understand is that when I just plug the STB to my HDMI Monitor (or TV) the remote presses are reliable.

I have purposely not mentioned instantaneous as sub has explained that the whole NPVR Client->NextPVR Server->IR Blaster (USB or Capture Card based)->STB->Capture Card->PC->Client->TV is slow, as above. I don't really care about the speed of the channel change TBH I don't channel surf (at least not right now).

However as I mostly watch recorded programs, I need to know it is going to be reliable and record the show I need.

I did a couple of trials as follows:

1. STB -> direct to HDMI Monitor, changing channels using STB remote - fastest changes (as expected) but also reliable; even after I did many changes sequentially.
   
2. STB -> [b]direct to HDMI Monitor, changing channels using USBUIRT (manual zap using cmd + a uutx batch) [/b]- reasonably fast changes (as expected) also reliable, even after I did many changes sequentially.
   
3. STB->Colossus in PC, NextPVR changing channels using USBUIRT (uutx-based batch) - slow changes (as explained) but unreliable, especially after I did a number of channel changes sequentially. I tried this with various permutations of "Restart on Live TV Channel Change" and "
   

• Why is (3) unreliable? See these pictures on another thread for examples of missing channel digits (1st, middle, last...).
  
• How do I improve the reliability of STB channel changing?
  
• What governs it?
  • Would a better / faster capture card (I have a Colossus I (HDPVR) which this thread suggests might be an issue?) take something out of the time needed for the change? I am more than happy to buy a new capture device if this will likely help.
    
  • Do IPTV STBs have some sort of buffer that needs to empty before you can "zap" the next channel
    
• My config.xml shows <HDPVRBufferLonger>false</HDPVRBufferLonger>. Would setting this to true help?
  
• My config.xml shows <WaitLongerDelay>6500</WaitLongerDelay>; would changing this help? Appreciate that referred thread back at 3.3.8 was fixed by sub via a patch for that posters problem.
  

Just upgraded to 4.2.4 and discovered the above mentioned. MPEG1 audio and LAV decoder, renderer(s) set to default. Are there any obvious pitfalls I'm not aware of?

Edit: Funny, after reviewing settings and saving them things seems to work ok again... ??

I always thought Nextpvr in Kodi was getting the Genre/Category from my XMLTV file. Looking at 3rd Rock from the Sun (listed as a Sitcom in my xmltv file) it is listed in the epg as Science Fiction/Fantasy/Horror. Similarly Bewitched an old 60's sitcom is also listed as Science Fiction/Fantasy/Horror. Some sitcoms are listed as Comedies although the xmltv file has a category of Sitcom. Just curious the source of what is being shown in the epg. Thanks.

Fresh install of latest NextPVR (4.2.4) with new Hauppauge WinTV DCR-3250 Cablecard Receiver on Windows 7 Pro 64bit system. Tuner paired with cable provider. Wintv web page (192.168.1.89) shows channels detected. Live TV/ Record works in Windows Media Center. But NextPVR does not detect receiver in setting>devices. Disabled Comodo firewall > no change. Network setup as Home Network.

Any suggestions for things to check? Logs attached.

Thanks

Updated to the latest NPVR Release and am now getting an Import Error when trying to reload my EPG XML.

Unable to read: xxxxxxx.xml
The Remote server returned an error: (500) Internal Server Error.

When i load the link in my browser the file downloads perfectly.

[ATTACHMENT NOT FOUND]

Your help is greatly appreciated.

Would anyone happen to know if there’s a way to get my Xtream-editor’s EPG inserted into NextPVR?

Hi All.
I have previously used NextPVR by directly connecting the PC to the TV. However, i now have a Sony Andriod TV. So figured Id load up Kodi and trial the PVR addon. However, I have loaded the addon only to be greated with "Add-on couldnt be loaded. An unknown error has occured". Is there something I am missing? is this supported on Andriod TV?

Kodi = 18.1

Thanks
