I understand now. I'll make a log tonight and send it to you.

When tuned to an encrypted channel, the firmware ignores the PIDs you 
specify via the tuning API, and instead decodes the program whose "program 
number" is set via the new ioctl call that I added. Hence the need for a 
patch to the program that does the tuning. It might be worth trying to tune 
to the encrypted channel with tuxzap instead of vdr, as I haven''t actually 
tested the vdr patch (I don't use the vdr program myself). After applying 
the patch you need to recompile libdvb, and then re-compile tuxzap.

The instructions tell you to remove the Technotrend drivers. But I think it 
comes with its own copy of the Technotrend firmware.

It's the version of the Convergence firmware from the 0.9.3 release.

I'll do my best, but of course I can't actually test anything with the 
AlphaCrypt CAM because I haven't got one.
