Problems after any firmware upgrade

As I said earlier the tip another member gave about mkvmerge seems to solve the “freezing” issue. However, on some movies I  find a less common glitch. A movie sound track will keep playing but the video will flip back to the movie start menu. “Resume” will bring the video back in.This will happen even if the MKV has been passed through mkvmerge.

I only experience these two problems with Handbrake 0.9.6.
