this was too fast it should be: http://mcentral.de/hg/~mrec/v4l-dvb-experimental
The code isn't tied to the em28xx in the experimental tree (it's used with cx88, saa7134 and em28xx) Best would be to look at em2880-dvb how it's implemented there. http://mcentral.de/wiki/index.php/Em2880#Installation the installation instruction for em28xx based devices should also apply for your version. best regards, Markus > > > I have the correct firmware for this card but I don't know how to > 'package' it to work with the 3028 driver. > > Where possible I certainly want to use reuse the existing code. > > The T750 is a SAA7134(5) based PCI card.
