This driver needs a copy of the Avermedia firmware. The version tested
is part of the Avermedia DVB-T 1.3.26.3 Application. This can be downloaded
from the Avermedia web site.
If the software is installed in Windows the file will be in the
/Program Files/AVerTV DVB-T/ directory and is called sc_main.mc.
Alternatively it can "extracted" from the install cab files but this will have
to be done in windows as I don't know of a linux version of extract.exe.
Copy this file to /usr/lib/hotplug/firmware/sc_main.mc.
With this version of the file the first 10 bytes are discarded and the next
