(not since my nexus-S with dual CI is not keeping up with the latest developments anymore). I now own a HVR4000, but Hauppauge are only supporting the USB CI for all new cards and apparently dropped the flatcable direct connection to a CI interface. There is software available to use a USB cardreader, which I am using now. This software however permits illegal distribution of keys as well. Interesting though is that this software doesn't use the official CI, nor a CAM, but a generic USB smartcard reader. If a solution could be developed, which is manufacturer independent, does not use a CAM and does not permit illegal use that would be great... regards, Johan
