Possble problems

• LOTS of debug messates- this can be turned off via a module parameters.
• Ignore IRQ - not sure.

• Side by side comparison with Airstar2/Air2PC_DVB showed signifcantly more errors in DigiTV's reception. (With antenna taken to DigiTv in, coax from DigiTv out to Airstar2 - signal was confirmed in optimal range from antenna).
