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, 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 an external software decoder to watch TV on your computer. Say Y if you own such a device and want to use it.
