The DVB Common Interface spec is quite complicated, and thus there's much source code dedicated to CAM handling in the firmware. What keeps us from fixing CAM related bugs is simply lack of time -- the developers having the required knowledge are busily working on drivers for totally different hardware. If it were easy to fix CAM support we'd already have done it. > So, what can we do to change this? Apparently the LinuxDVB users can't > do anything, because the driver firmware is "closed source".

What pay TV providers fear is the distribution of knowledge about the CA systems, not the distribution of binary only cruft that would enable you to pay them for their services. > To bring this posting to a conclusion, I'd like to ask the driver > developers: is there any interest on your side in making (all!) > CAMs work with LinuxDVB, just as they do with DVB under Windows? Interest: Yes. But I don't see it happening anytime soon. Sorry. > What can we (the LinuxDVB community) do to help you with this? I don't think it would be possible for anyone outside of convergence to work on the firmware, because of various NDA's. We could maybe try to use the Windows driver's firmware in our driver, but I guess that would break OSD support and maybe other parts of the API.
