A BT878 based DVB-T PCI Card produced and sold by Nebula.
Several versions of this card exist.
nxt6000 with bttv
(old version) just works with linux kernel 2.6.16. Direct comparison with AirStar 2 PCI / Air2PC DVB showed sigificant errors with drivers for DigiTv.
Successfully used with MythTV v0.19 to watch standard and high definition dvb free to air.

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 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).
