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
