I don't have a solution, but just to say that I have the exact same 
problem with UK DVB-T broadcasts, with the first program of the day, 
when I've got the timer to start a few minutes early, even with setting 
cutpoints around the offending periods. It seems both nuvexport, and the 
built-in Myth lossless transcoder (which I thought I would try to see if 
it would cut out the blanks), don't like this data. Plays fine in Myth
