Having done a bit of fiddling, the suggested whitelisting and the change to using Matroska with TVHeadend have fixed my issues 
So, thank you both very much for your suggestions.
The only thing I need to do now is work out how to calibrate the screen size for those it's using for playback.
Doing it for the front end is easy, but I don't know how to do it for the video resolution/refresh rates yet!
Thanks for the replies
I shall do some tinkering and will report back on my progress!
Nobody can help me with this at all?
Thanks in advance,
Chris.
Around my house I use 3 Raspberry Pi 4s, each of which has an official DVB hat fitted.
Two of them are connected to Samsung 4k TVs and the other to a Samsung HD TV. All are patched up to date and run Librelec 9.2.3.
Generally things are working well - but in order for TV programs recorded with TVHeadend to have sound in sync with the program I have found I am forced to set "Adjust display refresh rate" to Always and "Sync playback to display" to fix it.
However I have a very odd problem when watching other content because the audio sounds like it recorded on 'elastic' which is currently having its tension altered so the pitch is always changing.
This seems to happen with 2160P 24 frames per second recordings and 1080P 24 frame per second recordings alike. The video playback is fine.
Can anyone point me in the right direction as to what is going wrong please?
Thanks in advance!
Chris.
ps - In case its relevant I'm in the UK and TVHeadend records at 50fps.
Thank you for the responses.
On the contrary however I would suggest altering the TV/monitor settings on 4 different TVs twice a day is a pain!
Hi Everyone.
I'm running Libreelec 9.2 on a Raspberry Pi 4.
Can you tell me if anyone has done a blue light plugin for Libreelec along the lines of F.Lux please?
Thanks in advance,
Chris.
Thank you
That is working fine
Hi,
Can anyone tell me if it is possible to get the Netflix plugin working on a Pi4, and if so how to do so please?
Thanks in advance,
Chris.
Thank you. Even though I wasn't seeing any stuttering that does seem to have fixed the issue.
I also had the CEC crash on startup and as suggested swapping the cable to the other HDMI connector fixed it.
Thank you!
I have Libreelec running on a Pi4 with a DVB hat fitted. I enabled TV headend and from my desktop PC the channels are working fine.
On the actual Pi I can see all the channels and the video is fine but the sound is out of sync. Any ideas please?
PS thanks for all the great work on this
