I've found this happens when there's a "problem" with the original file
I want to transcode.  In my case, I have a couple of areas where things
break down -- I have recordings that start before a dvb-t channel begins
transmitting and recordings where the start of the recording is in a
different aspect ratio to the part of a transmission that I want to
transcode.  I've been queuing those recordings up in anticipation of a
solution occurring to me so haven't tried recently, but I think the
first one did cause exactly the problem you're describing.
