Slight stutter Live TV on one machine only

Every now and then Live TV on Kodi starts stuttering on my main machine. If I open Kodi on another machine and tune into the same channel it is flawless. But the tuners are attached to the main machine.
If I open up VLC or Windows Media Player and open the same channel it is flawless as well. If I close Kodi and reopen it I still have the issue. If I restart the machine the issue is fixed.

If this happens the machine is not very busy (CPU and memory are not used a lot)

Any idea?
