Regularly video and sound stuttering when watching streaming IPTV

[goonerista]

Hello
Just yesterday after years of great use one of my cwgtv's started to stutter when watching IPTV. It makes small stutter impacting both sound and video every ~50s. (when I timed it it was 53s,50s,58s,50s and 58s). I have two different apps (tivimate and iptv extreme pro) and its the same with both. My other cwgtv does not stutter, nor does my Samsung phone or my Windows PC (with the same sources of course). I have reinstalled both apps and reset the whole cwgtv to factory reset, switched wifi 5GHz to 2,4GHz and to wired ethernet. I have swapped the HDMI both in my receiver and plugged it into my Samsung TV. Same stuttering everywhere.
The series number is 09151HFDD0WYUB
Android 12
Kernel 14.9.269
Android TV OS STTK.230808.004.10714782
Id love any ideas.

Welcome to the club... I guess the problem is unsolvable. I have several boxes on Android, a firestick and there are no problems there. Unfortunately, Chromecast 4HD works exactly as you describe. I guess the firmware needs to be patched. All attempts to reset the device, WiFi network, etc. do not help.
