This morning I changed the source to 720p 60Hz and now it’s fine. I guess I can live with that for now, but it seems like the H264 decoder in conjunction with LiveTV is chocking on 1080p 60Hz. I’m happy to keep doing testing though.
I feel like I should explain my setup a bit. It’s probably unusual even for someone in the US. Because the US has such a fetish around copy protection, many cable companies encrypt all their channels and then set a little flag (the CCI byte) telling DVRs what they can do with the recordings. Unfortunately to use any other CCI byte besides COPY FREELY DVRs have to go through a very expensive certification process with Cablelabs, so only Windows Media Center did that. So to get some of my channels I have a cable box using component out going to a Hauppauge HD-PVR that converts that analog signal into a digital stream again. NextPVR is able to control that to do channel changes via a remote blaster. It’s the channels going through the HD-PVR that end up H264, and I don’t have any real control over that conversion. What I did to reduce it to 720p was change the cable box to only output 720p instead of 1080i (the HD-PVR must convert that to 1080p when redigitizing).
Anyway, thanks to everyone for suggestions, and I’m still hoping we can figure out what’s going on.
@pkscout i believe that if you are installing the July update, your issue with LiveTV at 1080p will be solved.
I had the same issue and it magically disappeared after July update.
Cheers 
Oddly my issue reappeared with the July update. It had been fixed in the previous update.
¯\__(ツ)_/¯
I’ve also been noticing stutters/skipping frames with TvHeadend where it wasn’t doing it previously. Happy to provide a debug log if it’ll help when I get home tonight.
Are there any updates and/or progress with this?
I am still experiencing sticking/stuttering with LiveTV. Would it be helpful to provide debug logs?
Can you update to the staging repository? The issue should be solved now.

Thanks Sam! Sorry how do I update to the staging repository?
Hi
Hopefully the issue is now addressed with the following commit:
I’d appreciate it if you could test this and provide feedback before we potentially release this as an update to other users. To test this update:
- Login via the command line
- Edit the file
/etc/apt/sources.list
- Add the following line:
deb http://apt.osmc.tv stretch-devel main
- Run the following commands to update:
sudo apt-get update && sudo apt-get dist-upgrade && reboot
- Your system should have have received the update.
Please see if the issue is resolved.
I also recommend you edit /etc/apt/sources.list again and remove the line that you added after updating. This will return you to the normal update channel.

Thanks i’ll update and do some testing. I’ll give feedback on what I find.
Actually – you’ll want to stay off the staging repository for now, as it contains elements for Linux 4.9.
Oh… Too late 
.
Is there an easy way to revert? And should I?
Are you sure you updated?
Is your system booting?
Please post a log.
I’m pretty sure that I updated successfully.
My Vero4k seemed to boot up fine and the LiveTV issue seemed to be gone…
I did get a sad face after stopping a liveTV stream so maybe that was related to the staging repository?
More than happy to post a log, but I’ll have to do it when I get home from work tonight.
OK here are some debug logs. Was literally getting them as you posted

That’s fine – just don’t update to staging again for now.

OK thanks Sam. I have removed the staging repository from /etc/apt/sources.list so I shouldn’t update to staging again.
Hi Sam, since I updated to the staging repository I have watched quite a bit of live tv and the issue appears to have been resolved! It is a pleasure to watch Live TV again 
.
Thank you for your work on this.
Glad to hear this. Thanks for confirming.
