  - ability to select between different tuners if the board has several
    tuners
  - abitility to select between different demux if the board has several
    demuxes
  - if frequency isn't specified, do not try to tune the tuner and
    assume some other software already did it
  - set a bigger buffer size to avoid packet losses
  - do not filter too many PIDs since some board only have 8 filters
  - kludged so that the module works perfectly well with the demuxstream
    demuxer
  - use DMX_PES_OTHER all the time because some boards do not have a
    decoder chip (this may be a problem for you)
