Slight Stutter

Just switched to Krypton and haven’t seen this issue prior, but there is a very slight stutter on occasion, noticeable when panning in movies.
I also notice on occasion when starting a movie a message stating “read rate too slow” but there is no further pausing or buffering.

Would an advancedsettings help this?

Running Windows 7 on a custom built HTPC. Playing movies from NAS, usuall 1080p mkvs

Thank you
