Could this be a plug in or trim automation lagging behind? -We've had some occasions where plugins are seconds late -then you roll back and play the same spot and everything is correct. For what ever reason we found having mxf files in the session made the issue more frequent.

Coalescing trims also seems to help.

Its a hard issue to pin down because there is always the thought that perhaps its the way it was mixed (even though you could swear thats not what you did) -its not until you can record to a stem and then compare you realize -sometimes (very infrequently) there are automation playback errors.

Anyway other than confirming that we experience this as well -not much help.

All the best
