Since the Filiago-Proxy is proprietary (binary-only), I don't know what
it does. I guess it joins one or more multicast-groups. It's possible
that the code which sets the DVB filters according to the multicast
addresses has bugs.

According to the Filiago FAQ the MAC is irrelevant because Filiago
uses multicast only.

The current DVB drivers from CVS try to get the MAC from the eeprom
on the card and use it as default. I don't know if the code which
reads the epprom is correct. If there is no label with the MAC on
the card, the only way to find it out is to boot Windows and install
the Windows drivers. The MAC should then be visible somewhere...
