HI,

Over the past two years I have built a library of MKV contained files which are now stored/shared between two GB Quads. Kids movies/programmes are used regularly. I updated from 3.808 to Helios 16. All MKV contained files are unwatchable - there is constant (prolonged) stutter.

This is what I have done to try and correct

Fresh flash Helios 16 - no settings restore (previous had Zeus so had saved settings backup) - issue remains
Fresh flash Helios 17 - settings restore - issue remains
Fresh flash Helios 17 - no settings restore - issue remains
Used November GB drivers - stutter stops but no audio (have toggled downmix options and rebooted etc)

Any ideas?
