Ok, it indicates at least that there is some problem but I'm not sure if 
it's the clock drift.
Have you locked how often SendDateTime is called and if it's called just 
before the CAM/Smartcard locks. I have a Alphacrypt too so I suspect 
it's more the smartcard's fault.

It's good to follow the spec but I didn't saw a clean way to pass the 
TDT to the CI/CAM classes. I'm also not sure if it is a good idea too 
mess with CI code from vdr since it makes a sync harder.
