I get around 50% CPU usage - it seems to be being taken up by the
demux code, invoked via a tasklet from the BT878 DMA interrupt.
Under these conditions I can't watch live TV (the video stream
gets corrupted).
But sometimes that drops to a few %, and everything works fine.
I have not been able to isolate any particular sequence of events
that provokes the switch from bad to good behaviour.
