+	  Support for PCI cards based on the Pluto2 FPGA like the Satelco
+	  Easywatch Mobile Terrestrial DVB-T Receiver.
+
+          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.
