As I can remember it was an update recently for MPCHC (not BE). That may be the cause. Have you tried it also with the previous version(s)?
(Regardless it's a bit strange and surprising to me, that it has just been suddenly updated, as if I recall it properly, the developers stated that they abandon the MPCHC project (or was it meant just a "suspension"?) ).
The only case I've experienced somewhat similar was with a DVD remux mkv, where I've have to add some delay to a custom audio track (to match up with the video) in MKVToolnix. The result was a back screen, with the counter stuck at 0:00, but in the instance I've pressed a bit the forward button it came to play back totally normally.
