+How to set up the Technisat devices
+===================================
+
+1) Find out what device you have
+================================
+
+First start your linux box with a shipped kernel:
+lspci -vvv for a PCI device (lsusb -vvv for an USB device) will show you for 

example:
+02:0b.0 Network controller: Techsan Electronics Co Ltd B2C2 FlexCopII DVB chip / Technisat SkyStar2 DVB card (rev 02)
+
+dmesg | grep frontend may show you for example:
+DVB: registering frontend 0 (Conexant CX24123/CX24109)...
+
+2) Kernel compilation:
+======================
+
+If the Technisat is the only TV device in your box get rid of unnecessary modules and check this one:
+"Multimedia devices" => "Customise analog and hybrid tuner modules to build" +In this directory uncheck every driver which is activated there. +
+Then please activate:
