It is supported under Linux.

Overview/Features

Several versions of this card exist .... and the differences between them are ??

Output of lspci -vnn:

Making it Work

Firmware

Drivers

(old version) just works with linux kernel 2.6.16. Direct comparison with AirStar 2 PCI / Air2PC DVB PCI showed sigificant errors with drivers for DigiTv.

Successfully used with MythTV v0.19 to watch standard and high definition dvb free to air.

kernel config

( I use menuconfig for kernel configuration) Select DVB:

 │ Symbol: DVB [=y]

Possble problems

  • LOTS of debug messates- this can be turned off via a module parameters.
  • Ignore IRQ - not sure.
  • Side by side comparison with AirStar 2 PCI/ Air2PC DVB PCI showed signifcantly more errors in DigiTV's reception. (With antenna taken to DigiTv in, coax from DigiTv out to AirStar 2 PCI - signal was confirmed in optimal range from antenna).
