Sorry to interfere in your discussion (i am still in learning mode)
Shouldn't you see some traffic in the stream MPEG encoder? When i do the
same test i get the following
   ivtv0: Stream encoder MPEG: 14% in use
   ivtv0: Stream encoder YUV: 0% in use
   ivtv0: Stream encoder VBI: 0% in use
   ivtv0: Stream encoder PCM audio: 0% in use
