Jonathan, As far as I know, one does not need special drivers to use BT-878 cards --they are already included in the distribution or available via apt-get. I may be wrong, though.
The decision about Epiphan was removing all the *specific* efforts that the scripts and the CA code made to be compatible with such cards. That means, in the case of the CA scripts, not fetching a list of available drivers from the Epiphan page, filter them according to the current kernel/architecture and prompt the user to choose one. In the case of the Java code, it meant getting rid of the "Kangaroo Patch" code, i.e., the code that dealt with signal losses in the card. Regarding v4l[2]src, from the 11.10 onwards there's no v4lsrc component in gstreamer anymore. Therefore, no matter if some video devices support the legacy v4l interface, now gstreamer only supports v4l2. The fact that v4l2 does not work in the Kangaroo Patch code was another reason to drop this part of the code completely.
