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