Hi Dorian
Yes. The PAL tuner module is a direct RF in/RF out device for all things not related to the TiVo signal, but note it is a powered passthrough so you need to have the TiVo on to get signal passed from RF in to RF out.
So daisy chaining the TiVo in the middle will not affect the decoding of NICAM on your TV for all non-TiVo channel reception.
