What I don't see here is whether VDR actually sends any CA_PMT descriptors to
the CAM. Are there any lines output when you switch to an encrypted channel,
as suggested under "8 Sending AOT_CA_PMT" in ftp://ftp.cadsoft.de/vdr/Developer/cams.txt ?

Well, it's hard to tell.
It would help a lot if you could in some way capture the data exchanged
between the program and the CAM under Windows, and list it in a similar
way than VDR. This helped me a lot when finding out why some CAMs worked
with the '-icam' firmware, but not with the "link-layer" version.
But I guess under Windows this is not really possibly... :-(
