It does seem to be to do with yadif=1/double framerate, I just tested 
three 5 minute samples recorded from a different channel hd/x264 this 
time and two of the three failed.

I know google will find patches that may help, but yadif=1/double fps 
doesn't feature with those streams, so maybe this is a separate issue as 
the streams are fine with yadif=0 or no yadif.
