PR8610 reduced buffering in codec which generally improved behaviour, but we have some reports of hard streams (like 3D BluRay) that now lag. The problem is when the codec's input buffer runs dry you waste useful decoder cycles. It seems adding another two frames of latency to decoder gets the performance back.
