My guide is working fine, but having added the channel icons they overlap with the channel names. Searching the posts reveals I could edit the guide.xml but I cannot locate the line(s) where to do this. Any ideas?
I have a new server I am standing up using truenas as the backend. Using nextpvr via docker, I am importing my IPTV using XC (my provider doesn't supply m3u directly anymore). I have no issues downloading the channels/guide but if I try to filter the groups on import, a popup shows up stating 'error!'. This only happens if I modify the groups. If I retick 'select all' at the top of the list, then the import happens no problem. It's only an error when I untick any of the groups. This is unfortunate as I only need a few select groups from the list and I get too much bloat otherwise (causing timeouts in my clients)
On Ubuntu, I have hosed my OS installation somehow. If I back up /var/opt/nextpvr/config.xml and /var/opt/nextpvr/npvr.db3 (I still have access via command line). And restore those files after reinstalling Ubuntu, will that restore everything, and if not, what would it not restore?
Is there a comprehensive guide to the lines in the config.xml file, particularly to the settings that aren't displayed in the settings UI? The wiki includes this page but there's not a whole lot of information there.
Many of the settings are self-explanatory or easily figured out, but others are mysterious to me as a NextPVR novice. In particular:
LastChannel: Currently set (by default?) at 0. What other settings are available, and what does the setting do or change?
OldStyleTimeLine: What does changing this do?
HDPVRBufferLonger: Does this control the length of the video buffer for owners of the HDPVR?
PreferredMenuStyle2: What does this setting mean?
ComSkipStartOffset and ComSkipEndOffset: Currently set to 0. What can I change them to, and what do they do?
ManualRecordingDays: Currently set to 10. What does this setting control?
ClientMode: Currently set to "false". What does changing it to "true" do?
CacheInLiveTVBuffer: Currently at "false". What does setting it to "true" do?
There are many other settings where the name is clear enough to my mind that no further explanation is needed, or clear enough that I can safely tinker with the setting, but the ones above stump me.
Lastly, in the web UI, what is "immediate skip" and how does it compare to any other kind of skip? What MCE button controls it, if any?
Thanks for any information that knowledgeable NPVR users might provide. As a side benefit, the info gleaned might be suitable for adding to the Advanced Configuration wiki page.
I set up comskip to run in parallel. I'll start playback 45-60 mins into a recording, and NextPVR will read from the EDL, and skip commercials, just like it's supposed to. Over time, NextPVR will gradually start the commercial skips earlier and earlier in time -- by the time I'm at the 2 hour (ish) mark, commercials are being skipped 5-10 seconds early, cutting off that much of the program (and playing that much of the commercial at the end of the skip period). If I stop playback and re-start from my saved position, commercials start getting skipped at the right time again. If I let the program finish and then start playback, the skip locations are correct from start to finish.
Any idea what's going on, and how I can fix?
I'm using Kodi with the NextPVR PVR Client addon. I've tested most on a Vero V OSMC device. My client is set to "Timeshift" Live TV Method, with a Pre-buffer time of 3 seconds, Live TV chunk size of 64, and Recording chunk size of 32 (I don't know what these options mean, btw, so if they're suboptimal, lmk). My device is on a local hardwired LAN with plenty of bandwidth between server & client.
The NextPVR server is running in the custom container published by @Ranbato , but I've been experiencing this behavior for years while I was running NextPVR on bare metal -- never brought it up before b/c it was just me using the frontend. Now family is getting involved ...

I have a TerraMaster NAS where I keep archived recordings. Archiving recordings to the NAS was failing (copying the files via windows explorer fails as well). (My old QNAP NAS did not have this issue. Here are the relevant lines from the NPVR log:

As a work around, I was able to use 7zip to zip and unzip the recordings, then I was able to archive them.
This issue was caused by the source NTFS files having alternate "streams" that are not supported by the destination filesystem (BTRFS or EXT4).
You can use this tool from Microsoft to remove them: https://learn.microsoft.com/en-us/sysint...ds/streams
Now I run this command on a nightly basis against the recording directory (via the updateepg script).
streams -s -d "D:\nextpvr"
If you simply want to check the files, remove the -d option:
D:\nextpvr>streams -s
I thought I'd try the SD 7 day trial. I've only tried once and it messed up a lot of stuff. Despite specifying UK, it download and imported a lot of channel/show data with German show titles and incorrect timings. I reverted to OTA EPG updates, emptied the EPG and manually updated - everything looked OK but several shows failed to record that night and the next day or two (this was earlier in the week and I haven't tried since).
Is it possible to see what npvr downloads BEFORE it imports so I can check it's valid? I had an email from SD this morning my trial finishes on Monday and I haven't really had a chance to see what it can do.
I've been running NextPVR on bare metal for some time, and now I'm switching to a Docker container. In doing so I'm learning more about NextPVR.
I think I understand that the /buffer dir is used to store a temporary (partial) copy of the mpeg stream being sent to the client. I think I understand it is also used to store the mpeg data stream being written as it is being recorded. Once the client is done playing back the buffered copy is destroyed; or when the recording finishes, the file in the buffer directory is written to the /recordings directory.
... do I have that right?
I'm asking b/c I'm trying to optimize the mappings of these directories to docker volumes / bind mounts. I currently have /recordings on a spinning-disk array, and I was thinking of putting /buffer onto an SSD, if that would make the experience snappier for clients. I have much more spinning disk space than I have SSD space, not surprisingly. For a machine that might at-most record 2 3-hour-long football games at a time
in 1080i at 15Mbps, and play back to 2 clients at a time, how much space would you think the /buffer dir need?
