FWIW, I'll probably soon start reverse engineering the budget CI to implement support in my Windows BDA minidriver. If any Linux programmer is interested in implementing support for Linux, contact me and we can help each other. What I have figured out so far: The MPEG-2 transport stream looped back from the CI is routed to port A of the SAA7146A. So switching from the direct stream to the decoded stream would be as simple as reprogramming the BRS configuration register, i.e. a single register write (plus a write to upload the register). The CI control seems to be wired to the SAA7146A DEBI port. I know very little about the CI protocol, it seems to be a rather complex beast :( But at least the low-level hardware access should be simple enough to figure out. The hard part is understanding the CI protocol enough to tell if the responses you get are correct, but that's pretty unrelated to the actual hardware implementation task...
