David,  
thanks for replying. I am testing the problem by manually added the show to mcebuddy. What is happening is when 5.3 or 5.4 launches fprobe it errors out with this below. It does not happen with 5.2. Now strangely I do have to Identical dell laptops that it works on one and not the other. Mcebuddy , hdhomerun, kodi is running on the same desktop server. What led me to this discovery is that when this errors out the program does a slow remux which takes for ever, it thinks it has an audio error.

I have run the same fprobe from mcebuddy\ffmpeg directory with same arguments with same show file locations and it runs and produces output. So I think permissions are correct. But it want run correctly with launched from 5.3 or 5.4.
