Error Messages in Log file

I get these error messages in my DVR log file while playing Oxygen. Any ideas? I have issues with this channel also while using Channels on the firestick 4k using hardware decoding. It crashes after around 30 minutes. I am using the Beta Update.

These are the errors that get listed in the log while using a wired connection to the Firestick.

2019/11/12 11:57:52 [WRN] Buffer for 1327134F ch644 is more than 95% full (clients=1, len=31877468)

What does the speed test button in the app report?

100 mbit/s The firestick is a wired connection

As you can see I get errors even when using Windows

Any ideas??

The messages shown in the first part are normal. What is happening when you view on Windows in the browser? Is it stalling or freezing there also?

I don't play it in Windows very often. Is it recommended to use Hardware or Software decoding using the Firestick 4k? I am playing a channel OAN (News Channel) on my Firestick using Hardware decoding and under the Windows DVR interface it doesn't show anything under activity? Is this normal?

Activity will only show up if Tuner Sharing is On. You can try setting that to Off and it will connect directly to the HDHR and won't cause the buffering errors shown on the DVR Log.

Hardware decoder is more performant but buggy. If its crashing then try Software.

I will check if Tuner Sharing is off or on.
Thanks
