+ Support for cards based on the SDMC DM1105 PCI chip like
+ DvbWorld 2002
+
+ 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 or M if you own such a device and want to use it.
