Three main chips is correct. The older card is an NXP TDA18271HD/C2
digital tuner, LG DT3304 atsc demodulator and eMPIA 2870 bridge
chipset. So this one isn't very different, just a newer demod and a
slightly different bridge chip. Both the demod and bridge chip should
be fully supported, so it should indeed mostly be a case of connect
the dots. Hopefully, its got a different usb device ID from the v1...
