Looking at another thread @Bobins was able to stop an issue with similar logging when he changed the NextPVR.exe settings from Auto to a fixed resolution. Maybe pick your resolution there.
The program NextPVR.exe version 1.0.0.0 stopped interacting with Windows and was closed. To see if more information about the problem is available, check the problem history in the Security and Maintenance control panel.
