Hardware MPEG video capture cards are capture/tuner cards wtih onboard MPEG 2 (or MPEG 4) video compression processors. As opposed to frame buffer tuner cards, they take up much less processor horsepower, since the CPU doesn't have to do the compression (the card's processor does that), and therefore more of them can be used on a single machine simultaneously.

One does still have to be concerned with the amount of allowable PCI bus traffic in a single chassi, even when using this sort of tuner card!!!
