Video playback stutters

I am running Krypton 17.3 and have recently noticed a problem watching .mpg files recorded using MythTV running on a separate system.

I have been running xbmc/kodi on this h/w for many years playing back these types of files without a problem. I haven’t changed any s/w or h/w recently other than stepping up from 17.2 to 17.3 and installing kodi-inputstream-adaptive.

The problem is intermittent and has occurred with several recordings – the picture begins to stutter and miss frames, the audio plays fine. Stopping and restarting playback sometimes fixes the problem.

A debug log is here http://paste.ubuntu.com/24923473/

Playback is fine initially then begins to stutter at 23:25 after a while I stop playback then restart at 23:38 and it plays fine to completion.

I hope the debug log has all necessary information, there are no addins configured and it’s the std skin. If you require further info let me know.
