Using a codec of type Long GOP, it is probably the rare I-frames that give the freezes. To find a solution you can use MKVToolNix (\url{https://mkvtoolnix.download/}) to correct and insert new keyframes into the mkv file (matroska talks about \textit{cues data}). It can be done even without new encoding. Or you can use the \texttt{Transcode} tool within \CGG{} because during transcoding new keyframes are created that should correct errors.
