A DVB-T PCI card produced and sold by Nebula.

Several versions of this card exist .... both using the Conexant Fusion 878A ??


nxt6000 with bttv

(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:

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).
