Wow, this problem is just driving me a little nuts. Has anyone here
seen anything like it? Here's the handbrakecli command used to
transcode the recordings:

/usr/bin/HandBrakeCLI -i $MYTHDIR/$MPGFILE -o $newname -e x264 -q 20.0
-l 480 -a 1,2,3,4 -E faac -B 160 -R Auto -f mp4 --detelecine --decomb
-m -x b-adapt=2:rc-lookahead=50

Any idea what could cause Mythtv to act like this on these files?
