This happen to me for the first time just last night with my HD-PVR.
Out of a 2 hour show, it only recorded 57 minutes.  I noticed it about
an hour and a half into the show when I walked by the HD-PVR and
noticed the blue light was not on.  According to MythTV, it was
actively being recorded and the logs did not show anything out of the
ordinary.  After the scheduled completion of the show, the logs showed
the recording finished on time.  However both the frontend as well as
MythWeb showed it was still recording.  Only when I restarted the
backend was a problem reported in the log.  Right now both the
frontend and MythWeb report the show is 2 hours 32 min in duration (I
restarted the backend 32 minutes after the scheduled end time).  When
I actually play the show, it shows 57 minutes in duration.

Here are the log entries that show the show ended on time as well as
the errors during shutdown:
