Oh, sorry, I must have missed that one.
Well, apparently VDR sends the CA_PMT then, so I'm even more puzzled why
it doesn't decrypt...

Well, anything is possible ;-)
Some providers of encrypted programmes go to great lengths to cause
problems for hackers in order to make it harder for them to illegally
watch their service - it wouldn't surprize me if they would break reception
for legal subscribers in the process, too...

However, since it works with Windows I assume there's either a problem
in the driver/firmware or VDR. But I'm afraid I can't see where it would be.
