+	  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.
