Support for PCI cards based on the Bt8xx PCI bridge. Examples are
the Nebula cards, the Pinnacle PCTV cards, the Twinhan DST cards,
the pcHDTV HD2000 cards, and certain AVerMedia cards.
the pcHDTV HD2000 cards, the DViCO FusionHDTV Lite cards, and
some AVerMedia cards.
Since these cards have no MPEG decoder onboard, they transmit
only compressed MPEG data over the PCI bus, so you need
