Mcebuddy was operating fine for about month and I noticed now that my h/w encoding which used to take 20mins is now taking 60 mins plus.

Any help appreciated

Taking a crack at this after a long time, from your logs:

ERROR> 2018-01-12T23:46:39 MCEBuddy.AppWrapper.Handbrake --> Hardware encoding appears to have hung, no progress in the last 300 seconds.
This is likely due to an unstable Intel Display Driver. Try updating or using a stable Intel Display Driver.
Terminating process.

Looks like your graphics driver may have updated and the new one is unstable and it’s falling back to software encoding. Try to use a recommended version.
