Thanks for beeing unhelpful.

tell me how I can download the logs from webos, please. Enabling logs is easy, but I cannot find ssh access to the lg tv.

[alexhass]

Additional detail. Playing recorded content of ZDF HD does not show the problem. But the backend server has no issue and is recording it… however something is different about live playing and play recordings of the same channel.

[alexhass]

Playing HD recordings also show a/v sync issues, but the stuttering every few seconds seem not exists.

Same issue on Android due to caching code changes.

another simple way is use kodi file manager and copy the file to a usb storage:

Sharing the full kodi log will share too much personal data in public. I'm not fine with this. Let me know what exactly you are looking for and I cut this from the logs.

Aside of this - every developer just need to add ARD HD or ZDF HD from SAT and he can see this with his own eyes. Always reproducible.

Seeing the exact same behavior on ChromeCast with GoogleTV (non 4K) and NextPVR with random HD channels, looking at the traffic to the device it seems like it can't cache faster than 10 Mbps (and the stream from memory usually sits at 20-25 Mbps from memory pre-update to Omega)

[Langelus]

Same issue on Android due to caching code changes.

Is there an issue logged with this? just curios

Yes but it was closed with a conclusion that it's my device problem.
