+ Support for PCI cards based on the Bt8xx PCI bridge. Examples are
+ the Nebula cards, the Pinnacle PCTV cards, the Twinhan DST cards and
+ pcHDTV HD2000 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.
