I suspect its using the following Philips components: - TDA8275 silicon tuner - TDA8290 PAL-NTSC demodulator - TDA10046 DVB-T demodulator .... this appears only on the P7134 "Dual" model, as you can see that it is absent in pictures of the non-dual P7134 model - SAA7131 audio/video decoder -- Cheers, CK
