ive read on this forum that the chipsets used in the pctv, pctv rave and pctv pro are the bt878 chipsets...but on the australian distributor site its states that these 3 crads use the bt8x8 chipset?? Is this just another name or an entirely different chipset? If all three cards use the same video capturing chipset..wouldnt it mean that all cards will capture as good as eachother or does one outshine the rest? thanks
