'Blackbird' is the 'code-name' given to Conexant's reference designs for MCE compatible video capture devices.
In the context plutohome uses the name 'blackbird' it means any PVR tuner card featuring the Conexant cx23416 MPEG encoder which isn't already supported by the IVTV driver project.
e.g. Leadtek LR6632 or Leadtek PVR2000 card and generally any card which uses the Conexant CX23416 encoder device (apart from PVR250, PVR350).
The card you have, frans, is a regular 'software' encoding card which does not have an onboard MPEG encoder. Drivers for your card (if available) can be found in the standard V4L code ( newbielink:http://www.linuxtv.org [nonactive]).
