  14           Here you can fine-tune some parameters of the CinergyT2 driver.
  15
  16           Normally you don't need to touch this, but in exotic setups you
  17           may fine-tune your setup and adjust e.g. DMA buffer sizes for
  18           a particular application.

  54           This is the interval for status readouts from the demodulator.
  55           You may try lower values if you need more responsive signal quality
  56           measurements.
  57
  58           Please keep in mind that these updates cause traffic on the tuner
  59           control bus and thus may or may not affect receiption sensitivity.
  60
  61           The default value should be a safe choice for common applications.

  82           If you have a very fast-repeating remote control you can try lower
  83           values, for normal consumer receivers the default value should be
  84           a safe choice.
